There is no doubt that sensory input on plantar surface of foot is important for gait and balance, but the real question is - do you have to feel an orthotic to get a kinematic or kinetic response (ie sensory input) ... my answer now is a big NO. We done several nerve block and ice to numb plantar surface of foot studies with and without orthotics - also tried orthotics covered wiht 40 grit sand paper to increase sensory input ---- we can find no differences in the response to foot orthoses in all those diffrent conditions.
