In summary I'm saying we are all free to choose what we believe and what makes sense to us as individuals - agree or disagree.
We are. And some people come on to academic forums and are unable to substantiate their claims and when challenged are incapable of forming a reasoned argument- agree or disagree?
What would be of interest would be take the study relating navicular drop to muscle fatigue. Have subjects particpate in a) barefoot running b) use of generic arch supports c) use of custome supports and d) use a priocpetive based insole
- test them at day 0 and then again at day 60 and observe changes.
You seem to have very quick acess to literature are you currently in an academic institute where this could be carried out?
You seem to have very quick acess to literature are you currently in an academic institute where this could be carried out?
No, I have spent the best portion of my life studying podiatric biomechanics. I am aware of the literature and I can use google- you should try it some time. In old fashioned parlance "I'm well read".
That reference, Mr Burke?
Some people know more about podiatric biomechanics than Mr Burke? Agree or disagree?
You make the assumption that I am incapable of carrying out the study because.... I am not currently attached to an educational institute........... I give you the law according to Burke: no one is allowed to carryout research outside of a educational institute. You fund it, I'll do it.
That reference?
Here's my advice to you Mr Burke: go read some and come back when you got some. BTW, my injury was caused by two blokes in-excess of 250lbs, probably pushing 300lbs each, hitting my knee simultaneously at full tilt during a rugby match. I don't think anyone on this planet could have developed enough muscular force to prevent an injury at that time. My muscles certainly couldn't protect my cruciate ligaments - but that's exercise for you.
certainly not - I would in fact encourage any and all to carry their own research through whatever means possible.
As I have said frequently - try it and you maybe be the proof. I have also said that sometimes academia does not promote free thought. By all means you or anyone is capbale of devising hypotheses and tests that should be logoical and therefore, to some extent, creditable and though provoking.
It is that determination and thinking out side of box that the world needs more of or will will never progress and evolve.
Sorry about your CL's - hopefully you still made the beer-up after the match
Sorry about your CL's - hopefully you still made the beer-up after the match
You're welcome to the last word Mr Burke, but your question "does any study show exercise is harmful" Results in a resounding yes. Now back to the original questions:
1) does any study show that traditional foot orthoses result in muscle weakness- not really. You were wrong there- yes, no?
2) Are there any studies which demonstrate that what you are advocating results in an increase in muscles strength?
To Craig
- You should be able to show me 3O. These philosophies, products and teachings are a 100 years old. There have been improvements to diagnostic tools, improvements in materials, improvements in manufacturing but the product and underlying philosophy are largely unchanged. Until some followers of Kapandji started practicing his teachings the 3 decade old views of Root dominated.
- There is room for change but it is hard, academia by and large rewards memory and regurgitation not free thought and new ideas. That’s why this is a fantastic forum. A nice study would be to repeat the study of Robbins and Hanna, but introduce a variable of “with orthotics”. Then make observations on cause and effect in foot morphology traits as well as kinematic measure.
So, in other words you con not provide one study to back up the claim that you made:
Quote:
There is considerable evidence out there illustrating that the ethics surrounding the use, over prescription, and successes with traditional foot orthotics is questionable.
Do you see why we cynical? Making up claims do not go down well around here. That why the 'snake oil' label gets attached to products that get promoted that way.
BTW, you do realise that weak instrinsic foot muscles actually cause a high arch foot ...

I am also of the opinion (of which I am entitled to and do not need to justify) that there are many factors in most conventional footwear that predispose them to be a less than ideal environments.
I agree that there are components of footwear designs which are not conducive to many individuals (& even to the act of running on the whole). This issue has been discussed before on this forum. However, I do have what some may consider unconventional opinions on this issue but apparently unlike you, I do feel the need to justify these opinions with a reason... i.e. based on cross referencing different research studies, personal experience & the observed structural design of the lower limb. I would have thought being that you...

Disagree (to a large extent)... very shaky grounds to base someone’s views/beliefs on matters such as this. What one feels is truth can be vastly different to another’s view of truth on the same topic... usually as a result based around our own personal world views... how we interpret a topic based on the 'glasses' (biases) we choose to view it with. This is why peer reviewing of research topics is a necessity.
Truth should not violate natural laws & principles in accordance with testifiable facts.

Totally agree with this comment... which is related to the previous quote/point. That being that some world views do contradict/violate natural laws & principles but are usually upheld & not allowed to be challenged due to some form of fear of the alternative consequences. Academia can even discriminate against someone for having an opposing view or even considering one, which may then challenge an established belief... some topics attract more dogmatism than others. Speaking of which...

It is this comment I'm particularly interested in. If you have some specific inside knowledge on this I would be particularly interested in it i.e. company, method of dispensing the device, type of 'custom' device etc... If you don't feel comfortable in publicly forwarding the information on a forum such as this then please contact me personally via the links here. Thank you.
I can't progress too well & 'evolve' to do something about it if you just sit on the information... can I?
I would not go as far as saying "snake oil". There is considerable evidence out there illustrating that the ethics surrounding the use, over prescription, and successes with traditional foot orthotics is questionable. Rememeber that this traditional approach is a century old, there are patents for arch support devices going back into the late 1800's, Dr. Scholl launched his first over the counter arch support in the early 1900's. Yet his own web site states that he recognized a link between patholgy and "weak" foot muscles prior to that.
A century ago the industry made a decision to cast, brace and support the weak muscles as opposed to strengthening them. Just because we did it this way for a 100years and many people have made millions of $$ doing so, does not make it the best way. We should always be looking for the better "mouse trap"
This is a fresh approach that is different. To say it is snake oil without doing the research into the muscle physiology, neuro-physiology and biomechanics that it is based on is a little unfair.
From what I see the approach plays on the properties of the GTO and muscle spindle fibres to create contractions and thus strengthen. A sound use of biofeedback and proriocpetive characteristics. Logically the repeated contractions will create stonger muscles, one bicep curl is not as effective as 5. Stronger msucles are better suited to deal with energy and thus can result in improved performance, reduced predisposition to injuury and the rehbailiation of injury.
If we brace the foot with a support and tighten it up inside a shoe I fail to see how that is going anything more than encouraging muscle atrophy. So the question is... do weak muscle perform better than strong muscles?
RBurke,
You've probably figured out that this group is pretty set in their way. I've tried to use experience, common sense, logic and thought on this forum and got no where. I'm sure you've figured that out by the recent exchange of posts you've had on this thread. Don't worry about the immature exchange of posts, it happens all of the time here.
Questioning the use of orthotics to the members of this forum and suggesting alternative approaches had me laughing out loud. With that kind of thinking, you are not about to get a warm reception from the people here.
I haven't read enough studies to understand why it is a good idea to wear big, heavy shoes stuffed with orthotics so I can't comment.
I have watched the athletic shoe industry evolve over the past 40 years. Currently, it is heading towards a path that contradicts the big, heavy shoe concept. The clients of the people on this forum will be wearing shoes that contradict the big, heavy shoe concept. Ignoring change does not mean it won't happen. It just means that those doing the ignoring have their head in the sand.
I am going to sit back and watch the show. Will the thought processes demonstrated on this forum become archaic and the people supporting them become dinosaurs? Time will tell.
You don't need to convince anyone here what you believe is right. For that matter, I'm sure you won't be able to, just follow your own ideas.
Dana,
who has been asked to mention at the end of my posts that I'm not a podiatrist and have no medical training. I guess that is in case you can't figure that out on your own.
Dana - can you not see that RBurke made some unsupported claims that are contradictory to the research evidence and then has totally failed to answer any of the questions put to them. RBurke has totally misrepresented the evidence and failed to respond when challenged on that.
Have you not noticed that they went away when a fundamental flaw was pointed out in their argument?
The product being talked about may or may not be any good, and I have no desire to find out. Given the nonsensical marketing claims and misrepresentation of the research, my 'snake oil' detector goes off. If it was promoted without that nonsense, I might be motivated to look closer at it.
BTW, this thread has nothing to do with "barefoot running". The thread is about a foot orthotics based on what the marketroids called "barefoot science"
We are not picking on "barefoot". We pick on anyone from any background who makes unsupported claims and claims that are contradictory to the evidence. See some of the threads about Podiatrists like Brian Rothbart, Ed Glaser and Denis Shavelson. They have been beaten up on also because of the nature of the claims that they make.

DaVinci, do we really know why they went away?
I know this thread has nothing to do with "barefoot running". I also know you are not picking on barefoot. I picked up on the defense of the church of podiatry and couldn't resist. BTW, just to make sure your assumption is correct about me, in addition to not being a podiatrist, I am not a barefoot runner.
I have seen how claims are supported, it wouldn't take much to improve on that process. Conducting studies that may or may not have some level of bias to support a claim leaves a lot to be desired. As well as grasping for studies that may only remotely and secondarily be related to support a claim is also pretty weak. Not having a supporting study does not mean reality doesn't exist either. It is laughable that you rely so heavily on studies performed in a controlled environment to separate what is real from what might be contrived. The problem is that a controlled environment is contrived.
Welcome Dana to this thread... given up on the “Barefoot Running Debate” thread have we? I must say I haven’t visited the thread lately due to the same old stuff being rehashed & repeated over & over again as a result of some who don’t want to leave their biases ‘at the door’ & take into consideration what has been said many times before.

Ummm, your perception is rather subjective isn’t it? Maybe others didn’t quite see it that way. Maybe others here feel they too have used (as you stated) “experience, common sense, logic and thought” & have felt they got nowhere.

“Immature exchange of posts”... like which ones? This comment has been the only immature piece I’ve seen here so far. Can you please provide examples of the immature posts? It should be easy for you to do – you just need to press the “quote” button below the post in question then state why it was “immature”. Thank you.

That is probably because you have failed to invest the time into understanding why orthotics is most definitely beneficial for some people/runners. Why orthotics are effective in reducing the adverse forces directed to an individual’s body region which is the primary cause behind that individual meeting their injury threshold too soon. There are of course alternative approaches to orthotic use for some injuries when orthotics are not going to address the primary cause for an individual. It is just orthotic therapy happens to be very effective in addressing a large percentage of the primary causes behind the multifactorial nature of running injuries. Other alternative solutions may be changing footwear, minor changes to running technique, stretches, strengthening exercises (i.e. plyometrics) etc...

I gave rburke a warm reception here. But in case you haven’t noticed yet, this is an evidence based forum. If something is said that has not yet been substantiated to some degree then questions will be asked. Is this not fair? Just because you or someone else finds it hard to substantiate your views with evidence doesn’t mean you should question the integrity of the forum members (or Podiatrists). I have asked rburke to provide evidence to the claims he has made. It really should be a simple task to complete... if he has the evidence. He has not done so! To receive the courtesy of a response would be nice – would it not?!
It would seem civility is only expressed in one direction with some people of a certain persuasion.

I view this as another immature generalised comment. I don’t believe in “big, heavy shoes” (see this post) but I certainly do believe in orthotics when used in the appropriate way (for reasons stated above).

I too believe that the “big, heavy shoe concept” isn’t appropriate – I have already stated this in this thread (here). However, I don’t feel others here (at least not the majority) are ignoring the change as you state. It is just it appears you only want to believe what you want to believe Dana, due to you own biases... thus your head could be termed “in the sand” on this issue.

Time should have already told you by now Dana – you just need to put aside your biases, open up your field of vision and grasp the diverse implications & expanse of the topic.

Well I’m a Podiatrist, a runner... & a runner who trains up to 180km/week in minimalist shoes (Nike Free 3.0), some of which are in modified Vibram FiveFingers.

Hmmm... you might get something from this catchy tune Dana...
All the best in your running & future reading/understanding on this topic.
Kind regards,
Matt.
Matt, thanks for welcoming me to this thread, until now, I wasn't sure if I could post to more than one thread or not. Glad we cleared that up.
You ask for an example of an immature exchange of posts. Reread posts 24, 28, 30, 32, 34, 36 and 38 of this thread. Look also at posts 648, 651, 653, 669, 671, 674, 676, 682, 692 in the Barefoot Running Debate thread. You can call those posts whatever you want, I know what I would call them. From those examples, I certainly understand your comment about old stuff being rehashed and restated over and over again. These are just two examples, would you like more? There are dozens and dozens of them on this forum.
It is possible that people go away because they are forced to prove their statements which they have no proof. I would also assume that people go away because they realize they are wasting their time. They figure out that they are trying to convince a group of people with a belief system that is based on their own interpretation of studies that they consider proof and nothing is going to change that belief system.
You said you gave rburke a warm reception. You said "Welcome to Podiatry Arena rburke. I hope you stay around long enough to answer some of the valid questioning of your views as well as substantiate them with credible references - it will only give your position & intentions credibility." There is probably a better adjective than warm to describe that quote.
You say this is an "evidenced based forum" yet when one of your Holy Elders stated "I will not recommend the Vibram FiveFinger shoe to runners since it does cause more metatarsal stress fractures to runners" I questioned the validity and credibility of this statement and got no response. What I found interesting is that none of the followers on this forum questioned this unsubstantiated statement. If it didn't come from one of your Holy Elders, I'd be willing to bet people would have been all over a comment like that. I can only conclude that the forum is evidenced based sometimes.
Matt, it is not about what I believe or what my biases are. I am simply genuinely interested in the thought trends with respect to running. When the barefoot and minimalist shoe trend started to gain popularity, I spent a lot of time reading about it primarily out of curiosity. It was only a matter of time before I stumbled on the Podiatry Arena and started reading what the opinions of this forum where with respect to this trend.
On this arena I read over and over about the unsubstantiated claims of the barefoot proponents. OK, no problem there, I get it. Then I started reading unsubstantiated claims from the very members of this forum about Vibram Five Fingers. I also started to read condescending comments such as the "church of barefoot". I had to laugh, some of the members of this forum where just as guilty about making unsubstantiated claims as those they where accusing.
I found what seemed to be total ignorance by people who claim to be medical professionals so outrageous that I went out and bought a pair of VFF the 3rd week in June. I had to see for myself what all the emotion and stink was about. After wearing them, I confirmed to myself that certain vocal members of this forum really had some strong opinions yet they had nothing to stand on. In spite of many having strong unsubstantiated opinions about shoes like VFF, they didn't even have experience to draw from.
Now that I have gained first hand experience with shoes like VFF, I have since began to wonder if the notion of supportive shoes that have room to hold orthotics that may also have motion control devices built into them really the best way to go? Physics tells me that to have what I just described, you can add heavy into the description. I can't help but wonder about the reaction many on this forum have to new shoes and products that hit the market. Are these people trying to protect something?
I have been asked what my agenda is. I in turn would like to ask what the agenda is of the people who have debated with me on this forum. My only agenda has been to point out that there are people here that are as guilty of spewing unsubstantiated bovine excrement as those they ridicule.
I have somewhat of a warped since of humor so when I read many of the posts written here, I have a good laugh. There are many here who think they have it all figured out. By spewing BS back and forth many have convinced each other that they have it all figured out. Sitting on the sidelines and reading this stuff is genuinely entertaining. Because of that, I'm probably not going to be as easy to chase away from this forum as you would hope.
You ask for an example of an immature exchange of posts. Reread posts 24, 28, 30, 32, 34, 36 and 38 of this thread. Look also at posts 648, 651, 653, 669, 671, 674, 676, 682, 692 in the Barefoot Running Debate thread. You can call those posts whatever you want, I know what I would call them.
Simon, ABSOLUTELY! You are one of my favorite members of this forum! It would be boring without you. Sorry, I can't provide references or substantiate those claims. Keep up the good work.

rburke came to this thread with a statement that there as plenty of evidence to support what they were claiming. Many barefoot runners have come to the thread on barefoot running with similar statements. They were all asked to produce that evidence. All of them failed to provide it. What has that got to do with belief systems? It has everything to do with misusing, misundertsanding, misinterpreting and misquoting (and in some cases lieing about) the research.

Craig, if someone came forward to this group with a claim that contradicted what people think on this forum and produced evidence to support that claim, based on what I have observed, I would expect some combination of the following to happen:
1) Members of this forum would look to discredit how the research was conducted.
2) Members of this forum would look to discredit the author(s) of the research.
3) Members of this forum would look to see how the research was funded and question it's credibility based on the sponsor.
I have no problem with the energy that has been put into discrediting supporting evidence of conflicting beliefs. I do have a problem when the same level of scrutiny is not placed on all evidence, including that in support of opinions and beliefs of this forum.
The problem with these studies that people seem to live by here, is that they are generally using small sample sizes over a small cross section of subjects in a contrived environment over a small time frame. The margin for error is huge, yet these studies are used it to project what is believed to be reality. Common sense tells you these studies are limited.
Never the less, if the study is supportive of the belief system, then is used as gospel and there you go. On the contrary, when someone references a study that supports something inconsistent with what is believed, then it is discounted as not credible. It seems like there are two piles of studies, those that support your beliefs = good, those that do not = bad.
Just today, Kevin referenced a study on another thread. I would love to read that study, it compares subjects wearing 5 different pairs of shoes vs barefoot. The study was conducted on different surfaces when wearing shoes vs not wearing shoes. I haven't had the opportunity to read the study but that seems like a gross flaw in what they are trying to demonstrate. I may be completely wrong on this, I haven't read the study. Why would you try to measure the differences between wearing shoes and not and have the subjects run on different surfaces?
Reality is filled with an infinite combination of possibilities. There will never be a study that addresses everything. Does that mean that if a phenomenon is observed that the phenomenon does not exist until there is research to support it? What I find unfortunate is that when someone comes to this forum who has observed a phenomenon, rather than try to understand what was observed, the person is badgered for supporting evidence. OK, but we all know supporting evidence is limited. Does that mean no one is allowed to report based on experience and observation? I guess not.
I'm not trying to argue whether the beliefs of many on this forum are right or wrong. I'm just surprised at how convinced some of the people here are that they are right.
My whole point being that I see a probability of next to zero that someone from the outside would be able to join this forum and convince the members here of something other than what they already believe. I don't care what proof or evidence they bring with them.
Dana, who is sincerely trying to understand the protocol that drives this forum.
I gave a whole lecture at the QLD State Conference last week on dealing with research that conflicts with your beliefs and experiences and the strategies to incorporate rather than ignore it. If the research stacks up to scrutiny, then it has to be incorporated into the practice, no matter which way the research goes. If the research stands up to scrutiny, you can’t ignore it no matter which way it points. I gave egs of how contradictory research can be incorporated and has to be incoporated.
That article posted by Kevin is not one of them and not relevant. The subjects weren't running, they were jumping from a height.
I would think we are equal opportunity here and critically appraise research no matter what it says.
Here is another eg: The barefoot running "church" are happy to dismiss any research done by or funded by the running shoe industry. Based on that why should any research done by barefoot runners or funded by a barefoot company be dismissed as well - they seem to like having it both ways. What is really amusing currently is how the barefoot "church" are going around praising that recent study funded by Nike .... can you explain why they are accepting the results of that Nike funded study when they are happy to dismiss the results of other Nike funded studies purely based on the source of funding. I really don't get it!
Here is another eg: Have a read of this, especially the bit were two barefoot running websites run the headline that "running shoes cause osteoarthritis". No matter what the "world view" view is, they made those claims up. Why did they do that for? (the study they were quoting was not even done on people with osteoarthritis!)

Craig, From what I've read, those talking about barefoot running have really taken the wrong approach and have made idiots out of themselves. What is unfortunate is that if their ideas about barefoot running or wearing ultra light shoes have merit, it has been detracted from because of the way it has been presented.
I really don't disagree with people discrediting the barefoot proponents because of their approach. What is unfortunate is that with the desire to discredit the approach, the concept of minimalism that may or may not have merit is also discredited. One of my points has always been that just because a supporting study does not exist, it doesn't mean the idea is without merit.
I can't sit here and whip out studies for or against running with shoes or without. Because I am fortunate enough to see for myself, I certainly have a good idea of what works for me. Yes n=1. It doesn't matter what works for everyone else, it is n=1 that I'm interested in. I have read enough to know what the barefooters have to say. I have read enough to know what many of the podiatrists on this forum have to say. I also have my own brain, a ton of experience and I know what to think about what works for me. That is good enough for me.
In the end, none of this matters, I'm going to do what Dana wants to do. All of my discussion is just my observation of the reaction this forum has had to the barefooters and to shoes like VFF. If you feel the reaction has been appropriate, fine. I know I won't convince anyone differently.
The thing that really bothers me about the site "Barefoot Running is Bad", is that the author remains anonymous. My guess is that whoever owns the site is also a member of this forum because it is all too familiar. Whoever it is, since they are reluctant to put their name behind what they have to say, I'm reluctant to waste my time reading it.
What has been great for me is that if it wasn't for this forum getting so worked up over the barefooters, I probably never would have tried truly minimalist shoes. I was always under the premise that highly cushioned and supportive shoes are good. What I have found based on my own desire to learn and my fortune of being able to open my mind briefly to try minimal shoes is that the premise of cushioned, supportive shoes for the mainstream may actually be wrong or at least wrong for Dana. It will take time for me to tell.
Dana, who is grateful to have a civil discussion with you Craig, thank you.
You ask for an example of an immature exchange of posts. Reread posts 24, 28, 30, 32, 34, 36 and 38 of this thread. Look also at posts 648, 651, 653, 669, 671, 674, 676, 682, 692 in the Barefoot Running Debate thread.
Crikey, they're all Simon's posts Nothing like a bit of friendly banter.

Ummm... constructive . Anyway, the welcome was sincere.

Yes, I would question this to some degree as well - & have (last two paragraphs). Wolf's law would address this issue if adequate adaptation is conducted.

It was only a matter of time before I stumbled on the Podiatry Arena and started reading what the opinions of this forum where with respect to this trend.
I sincerely commend you on your efforts & interest on this topic.

I too brought a pair about 3-4 years ago with the prediction there would likely be a lot of "emotion and stink" regarding them. I believe there can be a place for them in training for some runners (not all). I wouldn't race in them however. I commend you again for the interest invested in the topic.

I have already expressed my view on the validity & importance of orthotics for some people (& in some circumstances). However, I too have questioned the validity/function of 'supportive' shoes. I believe most (probably except very heavy runners who have poor lower limb function) runners do not need them - in fact they may well be contributing to adverse gait/lower limb function.
As far a weight of the shoe is concerned - I believe in training, it is advantages to increase metabolic cost in some sessions (i.e. weighting the lower limb would contribute to this) whilst allowing the lower limb/foot to function uninhibited as possible. However, the objective for racing is to decrease the metabolic cost as much as possible (i.e. decreasing weight, improving lower limb function & muscle efficiency/loading).

You are hardly sitting on the sidelines. Despite this forum appearing to act like a boys club, I certainly have no intentions of chasing you away (& I would like to believe nobody else is either). I welcome your contributions when I get the time to read them.
Craig, From what I've read, those talking about barefoot running have really taken the wrong approach and have made idiots out of themselves. What is unfortunate is that if their ideas about barefoot running or wearing ultra light shoes have merit, it has been detracted from because of the way it has been presented.
I really don't disagree with people discrediting the barefoot proponents because of their approach. What is unfortunate is that with the desire to discredit the approach, the concept of minimalism that may or may not have merit is also discredited. One of my points has always been that just because a supporting study does not exist, it doesn't mean the idea is without merit.
I can't sit here and whip out studies for or against running with shoes or without. Because I am fortunate enough to see for myself, I certainly have a good idea of what works for me. Yes n=1. It doesn't matter what works for everyone else, it is n=1 that I'm interested in. I have read enough to know what the barefooters have to say. I have read enough to know what many of the podiatrists on this forum have to say. I also have my own brain, a ton of experience and I know what to think about what works for me. That is good enough for me.
In the end, none of this matters, I'm going to do what Dana wants to do. All of my discussion is just my observation of the reaction this forum has had to the barefooters and to shoes like VFF. If you feel the reaction has been appropriate, fine. I know I won't convince anyone differently.

Dana, who is grateful to have a civil discussion with you Craig, thank you.
That article posted by Kevin is not one of them and not relevant. The subjects weren't running, they were jumping from a height.
Craig:
The barefoot versus shoes study I posted recently in the Barefoot Running Debate thread was, indeed, about running, not about jumping from a height (Braunstein B, Arampatzis A, Eysel P, Bruggermann GP: Footwear affects the gearing at the ankle and knee joints during running. J Biomech, 43:2120-2125, 2010.)
Quote:
Abstract
The objective of the study was to investigate the adjustment of running mechanics by wearing five different types of running shoes on tartan compared to barefoot running on grass focusing on the gearing at the ankle and knee joints. The gear ratio, defined as the ratio of the moment arm of the ground reaction force (GRF) to the moment arm of the counteracting muscle tendon unit, is considered to be an indicator of joint loading and mechanical efficiency. Lower extremity kinematics and kinetics of 14 healthy volunteers were quantified three dimensionally and compared between running in shoes on tartan and barefoot on grass. Results showed no differences for the gear ratios and resultant joint moments for the ankle and knee joints across the five different shoes, but showed that wearing running shoes affects the gearing at the ankle and knee joints due to changes in the moment arm of the GRF. During barefoot running the ankle joint showed a higher gear ratio in early stance and a lower ratio in the late stance, while the gear ratio at the knee joint was lower during midstance compared to shod running. Because the moment arms of the counteracting muscle tendon units did not change, the determinants of the gear ratios were the moment arms of the GRF's. The results imply higher mechanical stress in shod running for the knee joint structures during midstance but also indicate an improved mechanical advantage in force generation for the ankle extensors during the push-off phase.
There were 14 experienced runners that ran barefoot and in five different types of shoes ( the exact types of shoes were not listed) at a 4.0 m/sec pace (6:42 mile pace) over a force plate while on a tartan track surface (shoe conditions) and a grass surface (barefoot condition) in this study from University of Cologne and University of Berlin, Germany. They used 3D video along with inverse dynamics to determine the moment arm length across the ankle joint axis and knee joint axis for both ground reaction force (GRF) and the quadriceps and gastrocnemius-soleus to come up with a "gear ratio" which was GRF moment arm length/muscle moment arm length.
They found that running barefoot increased the gear ratio at the ankle joint in early support phase but decreased the gear ratio at the knee joint during the middle of support phase. Running in shoes also significantly increased the moment arm length for the ankle plantarflexors during propulsion (speculated due to increased MPJ stiffness with the shoe vs. barefoot) which may have led to reduced shortening velocities for the ankle joint plantarflexors during propulsion. This is the first study I have seen that actually measured moment arm lengths of barefoot vs shod running and may help explain how barefoot running may actually aid some people with some types of chronic knee injuries to run less painfully than while in shoes. In addtion, when combined with Benno Nigg and Darren Stefanyshyn's research on running efficiency with stiff-soled running shoes (remember Benno's prediction of a world record in his shoe for the 2000 Sydney Olympics?) this research may help explain why running in shoes may actually be a faster way to run than running barefoot. Very interesting!!

Increased shoe bending stiffness increases sprint performance
Authors: Darren Stefanyshyn; Ciro Fusco

Abstract
The purposes of this investigation were to determine if increasing the bending stiffness of sprint shoes increases sprinting performance and to determine whether simple anthropometric factors can be used to predict shoe bending stiffness for optimal performance. Thirty-four athletes were tested using four different shoe conditions — a standard condition consisting of their currently used footwear and three conditions where the bending stiffness was increased systematically. The sprinters performed maximal effort 40 m sprints and their sprint times were recorded from 20 to 40 m. On average, increasing the shoe bending stiffness increased sprint performance. The stiffness each athlete required for his or her maximal performance was subject specific but was not related to subject mass, height, shoe size or skill level. It is speculated that individual differences in the force-length and force-velocity relationships of the calf muscles may influence the appropriate shoe stiffness for each athlete to obtain their maximal performance.

RBurke,
You've probably figured out that this group is pretty set in their way. I've tried to use experience, common sense, logic and thought on this forum and got no where. I'm sure you've figured that out by the recent exchange of posts you've had on this thread. Don't worry about the immature exchange of posts, it happens all of the time here.
Questioning the use of orthotics to the members of this forum and suggesting alternative approaches had me laughing out loud. With that kind of thinking, you are not about to get a warm reception from the people here.
I haven't read enough studies to understand why it is a good idea to wear big, heavy shoes stuffed with orthotics so I can't comment.
I have watched the athletic shoe industry evolve over the past 40 years. Currently, it is heading towards a path that contradicts the big, heavy shoe concept. The clients of the people on this forum will be wearing shoes that contradict the big, heavy shoe concept. Ignoring change does not mean it won't happen. It just means that those doing the ignoring have their head in the sand.
I am going to sit back and watch the show. Will the thought processes demonstrated on this forum become archaic and the people supporting them become dinosaurs? Time will tell.
You don't need to convince anyone here what you believe is right. For that matter, I'm sure you won't be able to, just follow your own ideas.
Dana,
who has been asked to mention at the end of my posts that I'm not a podiatrist and have no medical training. I guess that is in case you can't figure that out on your own.

From those examples, I certainly understand your comment about old stuff being rehashed and restated over and over again. These are just two examples, would you like more? There are dozens and dozens of them on this forum.
It is possible that people go away because they are forced to prove their statements which they have no proof. I would also assume that people go away because they realize they are wasting their time. They figure out that they are trying to convince a group of people with a belief system that is based on their own interpretation of studies that they consider proof and nothing is going to change that belief system.
You said you gave rburke a warm reception. You said "Welcome to Podiatry Arena rburke. I hope you stay around long enough to answer some of the valid questioning of your views as well as substantiate them with credible references - it will only give your position & intentions credibility."

What I found interesting is that none of the followers on this forum questioned this unsubstantiated statement. If it didn't come from one of your Holy Elders, I'd be willing to bet people would have been all over a comment like that. I can only conclude that the forum is evidenced based sometimes.
Matt, it is not about what I believe or what my biases are. I am simply genuinely interested in the thought trends with respect to running. When the barefoot and minimalist shoe trend started to gain popularity, I spent a lot of time reading about it primarily out of curiosity. It was only a matter of time before I stumbled on the Podiatry Arena and started reading what the opinions of this forum where with respect to this trend.
On this arena I read over and over about the unsubstantiated claims of the barefoot proponents. OK, no problem there, I get it. Then I started reading unsubstantiated claims from the very members of this forum about Vibram Five Fingers. I also started to read condescending comments such as the "church of barefoot". I had to laugh, some of the members of this forum where just as guilty about making unsubstantiated claims as those they where accusing.
I found what seemed to be total ignorance by people who claim to be medical professionals so outrageous that I went out and bought a pair of VFF the 3rd week in June. I had to see for myself what all the emotion and stink was about. After wearing them, I confirmed to myself that certain vocal members of this forum really had some strong opinions yet they had nothing to stand on.

I have been asked what my agenda is. I in turn would like to ask what the agenda is of the people who have debated with me on this forum. My only agenda has been to point out that there are people here that are as guilty of spewing unsubstantiated bovine excrement as those they ridicule.
I have somewhat of a warped since of humor so when I read many of the posts written here, I have a good laugh. There are many here who think they have it all figured out. By spewing BS back and forth many have convinced each other that they have it all figured out. Sitting on the sidelines and reading this stuff is genuinely entertaining. Because of that, I'm probably not going to be as easy to chase away from this forum as you would hope.

2) Members of this forum would look to discredit the author(s) of the research.
3) Members of this forum would look to see how the research was funded and question it's credibility based on the sponsor.
I have no problem with the energy that has been put into discrediting supporting evidence of conflicting beliefs. I do have a problem when the same level of scrutiny is not placed on all evidence, including that in support of opinions and beliefs of this forum.
The problem with these studies that people seem to live by here, is that they are generally using small sample sizes over a small cross section of subjects in a contrived environment over a small time frame. The margin for error is huge, yet these studies are used it to project what is believed to be reality. Common sense tells you these studies are limited.
Never the less, if the study is supportive of the belief system, then is used as gospel and there you go. On the contrary, when someone references a study that supports something inconsistent with what is believed, then it is discounted as not credible. It seems like there are two piles of studies, those that support your beliefs = good, those that do not = bad.
Just today, Kevin referenced a study on another thread. I would love to read that study, it compares subjects wearing 5 different pairs of shoes vs barefoot. The study was conducted on different surfaces when wearing shoes vs not wearing shoes. I haven't had the opportunity to read the study but that seems like a gross flaw in what they are trying to demonstrate. I may be completely wrong on this, I haven't read the study. Why would you try to measure the differences between wearing shoes and not and have the subjects run on different surfaces?
Reality is filled with an infinite combination of possibilities. There will never be a study that addresses everything. Does that mean that if a phenomenon is observed that the phenomenon does not exist until there is research to support it? What I find unfortunate is that when someone comes to this forum who has observed a phenomenon, rather than try to understand what was observed, the person is badgered for supporting evidence. OK, but we all know supporting evidence is limited. Does that mean no one is allowed to report based on experience and observation? I guess not.
I'm not trying to argue whether the beliefs of many on this forum are right or wrong. I'm just surprised at how convinced some of the people here are that they are right.
My whole point being that I see a probability of next to zero that someone from the outside would be able to join this forum and convince the members here of something other than what they already believe. I don't care what proof or evidence they bring with them.
Dana, who is sincerely trying to understand the protocol that drives this forum.
Dana,
I know I've probably said this before but I find some of your posts presumptuous and bordering on the patronising. You seem to judge the arena community (and by the sounds of it the Podiatry profession) solely based on the posts made here. You know very little about any of us or the theories we subscribe to. Why? Because most of us can keep objective when we critique research and post here. You don't think any of us have even tried a pair of VFF's, despite both myself and Ben-Hur previously telling you that we own a pair (and I'm sure we are not the only 2 Podiatrists who do).
Why is the Podiatry profession so fixated on critical appraisal of research? I don't know. Maybe as there seem to be so many 'get fixed quick' schemes focusing on the lower limb. As Craig has said it is not a barefoot/minimal thing - we are just as critical of our own kind who make unsubstansiated claims regarding foot orthoses, not to mention footwear which promises things which are not yet proven (MBTs, Fit Flops, Shape Ups, Easy tone etc etc).
Finally, I would have thought you had been around long enough to have frequented more than a few online forums Dana. You should therefore realise that there is a certain theme which they all have irrespective of whether they are a forum about Podiatry, Knitting or your favourite NHL team. They all have regular posters. Those posters all have individual personalities. Any relative newcomer posting will always feel like there is a clique or a gang which they are not a part of. No forum will take too kindly to relative newcomers pretending to know more than they do - particularly when it is the bread and butter of the regular posters. Want a classic example? See this post from a Cycling forum. (If you have a spare 30-40 minutes try to read all the posts - there are some rather amusing ones).
My point is: stop making Podiatry Arena out to be a clique of bullies who resist any involvement from non-regulars. You and I both know that is not the case. It's no different to any other forum. Fact. If you are going to stay around (which of course you are more than welcome to and I hope you do) then stop bleating on about it like an old woman and just deal with it.
You don't think any of us have even tried a pair of VFF's, despite both myself and Ben-Hur previously telling you that we own a pair (and I'm sure we are not the only 2 Podiatrists who do).
Ian, I've made the implication about the members of the forum not trying VFF's purposely. My expectation was that I would be corrected and in the process find out if anyone on this forum really has tried the shoes. Until Matt and you just surfaced, no one has admitted it. I find that curious because the discussion about barefoot running and minimal shoes has been going on for a long time! I don't know if there are only 2 of you on the whole forum or if there are more. You are sure there are more, with all of the discussion about VFF, I find it amazing that more people haven't come out of the closet and admitted wearing them. Why do you think that is?

Ian, will do. I have more than had my say. It will be all about going forward from here.
with all of the discussion about VFF, I find it amazing that more people haven't come out of the closet and admitted wearing them. Why do you think that is?
I don't know Dana. I cannot speak for anyone else. Personally I didn't feel it necessary to mention in every post I made that I wear them on a weekly basis. Maybe as I know we don't hugely value anecdotal/n=1 evidence. I find them quite comfortable. However I spoke to a colleague who got raging knee pain from using them. Exchanging these sort or personal yarns doesn't really get us anywhere with respect to truely understanding the potential risks/benefits does it?
As I said, I do not need to 'admit' what I do in my own time in order to appropriately critique research - it shouldn't (and doesn't) change the way I view evidence. Something perhaps a portion of the barefoot community could take on board?
