Good post Bob,
Interesting.
No mention of transverse plane torque at all, so the "shoe engineers" are just going for optimum cushioning (and I'd like to see how they worked out what "optimum cushioning" is).
Have the shoe designers taken into account that knees have a natural mild coronal plane valgus angle, or that this may increase depending on extrinsic factors (terrain), and intrinsic factors (biomech anomilies), or that increased valgus angle may account for a high % of knee pain

?
Given that the writer doesn't mention any of this, I assume they haven't.
The clinch line is at the end of the "article" - these are the "coolest shoes
around" etc etc.
Nice design feature - not much more.
Regards,
David
