Thank you Bart and Howard for your responses.
I recently came across a paper,
Robbins S, Waked E, Rappel R : `Ankle taping improves proprioception before
and after exercise in young men` - British journal of Sports Medicine
29(4) 242-7 , 1995 Dec.
Here the authors believed that inadequate foot position awareness was a
major cause of ankle sprains.
According to their study they concluded that ankle taping partly corrected
the impaired foot proprioception incurred by athletic shoes.
There have also been a number of studies regarding proprioception and
stability, therefore it is surely feasible that this can be extrapolated to
the functioning of how foot orthoses may impart their effects.
What do you reckon, Spoonz ??
