Orthotic Shoe Inserts May Work, but It's Not Clear Why

Leading orthotics researcher, professor of biomechanics@ Human Performance Lab @ Univ. of Calgary,Alberta. His conclusion: orthotics may be helpful as a short-term solution, preventing injuries in athletes. But it’s not clear how to make inserts that work. The idea that they are supposed to correct mechanical-alignment problems does not hold up. The work of THE GAIT GUYS, hopes to offer some insight.
Ivo Waerlop A potential riff in the article (Via Stu Currie):

1) Primates only have a transverse arch – they are flat in the longitudinal direction.

2) In primates the metatarsal bases are on the same plane as the metatarsal heads.

3) The length of the phalanges is 18% of total foot length in humans, and 35% in chimps.

4) Australopithecus afarensis (Lucy) has the beginning features of a longitudinal arch, while retaining many characteristics of the ape foot. The same can be said for other hominid ancestors (H. Habilus)

Ivo Waerlop We have always said that orthotics serve as a therapy, not a solution. Your prescription should be getting better (lessening) or more correction taken out with time, not becoming greater. They are an excellent tool, but not a substitue for good mechanics.
