ABSTRACT:
A shoe incorporating dynamic Orthotic means which adapt to the foot in a prescribed manner, controlling heel "strike" and weight bearing loads, establishing a cup-shape to "catch" the heel and foot to stabilize it, balancing and maintaining the sub-talar joint in a neutral attitude and the mid-tarsal joint locked, enabling the foot and ankle to maintain optimum integrity as an efficient support and propulsion system, and resisting the symptomatic tendency for the sub-talar joint and foot to overcompensate and overstress the anatomy.
