I have a pair of orthotics and they are relatively new. However, the hard shell on the bottom is starting to separate from the spenco type top. It isn't serious but I want to do a simple repair to prevent any further damage.
What would be a good adhesive to bond the spenco type top to the plastic bottom?
Some one suggested super glue or shoe goo, but I am not sure they would be suitable for this purpose.
How old are the orthoses? If they are relatively new as you suggest most labs have a warranty on top covers. Return it to the Podiatrist who will send it back to the lab for a refurbishment.
Honestly I am looking for a solution so I don't have to send them out and wait for more than 1 day (so the adhesive can dry). I am looking for a in-house or at home solution. Thanks.
Use any contact adhesive ie: Quick Grip. (you'll only need a small tube)
If you've got any acetone, clean the old glue off first, then brush a small amount of glue, evenly on both sides of the Spenco. Make sure you keep the materal seperated! Wait for it to be touch dry then stick it down. For better results, heat the area (not too much!) with a hair dryer on hot before sticking it.
Cheers,
Neil

Ok no problems - then take Neils advice above, he is one guy who would know!!!
Quikgrip is quick, easy and effective. Add a pair of surgical scissors, 7mm adhevise felt, selection of 4mm Heel lifts, RF wedges and Met domes, a variety of top covers, along with a grinder, allows virtually any in-house orthotic mod / repair.
Any Practitioner whom interacts with prescription orthoses must be able and equipped to modifiy / repair them in clinic, usually during consultation.
don't use a super glue or shoe goo. A contact cement is what you need. I fabricate orthotics and that is what I use. Also if the shell is smooth, rough it up with a 80 grit sandpaper to get a better bond.

Thanks for any help that can be provided.
You want to use a contact cement on orthosis topcovers. You can use rubber cement but it won't last very long. I use Barge cement in the office. It is very durable. You can also just go to the local hardware store, ask for a contact cement, and use that....it will work just fine.

Reason I ask is that Kevin has recommended Barge cement, unfortunately it's not available in the U.K.
We currently use Renia colle de cologne, it works well for neo top cover to polypro shell.
I would recommend that you remove the old adhesive with acetone based remover and abrade the surface with high grit sandpaper then wash and dry thoroughly before applying a thin, even coat of adhesive to both the poly shell and spenco/neo topcover, wait till touch dry, heat reactivate and bond from distal- shell tip to proximally- heel cup, take care to avoid air bubbles.
I agree with Scott. With much personal experimentation, the German orthopedic cements have been clearly more versatile and reliable compared to all the others we tried in our lab (Barge and Masters included).
Renia makes a cement called Ortek that is reliable and maintains its viscosity well. The good thing about Colle De Cologne is the flexibility in adding appropriate modifiers to it. This cement coupled with their PU primer is indispensable when working with modern orthopedic footwear. In your particular case I would expect the Red hardening agent would supply the hold you need while maintaining appropriate flexibility.

What is a good contact adhesive available in Australia? I have been using a product through a vinyl/material supplier but it is not always a convenient way to buy & I thought maybe a Bunnings or similar might have some suitable options.
For a supllier try www.leffler.com.au good prices and delivery and if you are a member of the APMGFA you get an extra 20% off list price on all materials.
Also Algeos have some good adhesives too.
When we use a neoprene based adhesive we apply to both surfaces, dry a little with the heat gun and stick the cover on whilst it is still warm and its back in the clients shoe in 10 min. once it has cooled, very quick this time of year
