Abstract
A forward recovery foot support system for any shoe but primarily for running and jogging shoes. The system includes a base conforming generally to the contour of a human foot, a first ray extension attached to the base and extending substantially only under the first proximal phalanx of the foot, a fifth ray extension attached to the base and extending substantially only under the fifth proximal phalanx of the foot, and a heel post attached to the base and extending substantially only under the heel bone and providing added elevation at the most lateral aspect of the heel bone to compensate for the natural inversion of 2.degree.-3.degree. that is present in most persons' heels. This support can be designed as an insert independent of a conventional shoe sole or may be incorporated into the sole of a shoe.
