ABSTRACT:
A shoe having a resilient strap running from under the forefoot to a rigid heal counter is provided. The shoe is constructed such that a fulcrum is provided under the strap so as to create a windlass effect during the normal walking cycle. This effect results in providing added support for the longitudinal medial arch of the wearer of the shoe.
