ABSTRACT:
Disclosed herein is an energy managing shoe sole construction wherein, during the stance phase of the wearer's gait cycle, the impact energy of the heel strike is absorbed, stored and, at least in part, returned to the underside of the forefoot during the propulsive phase of the gait, thereby aiding in the locomotion of the wearer. Following the propulsive phase of the gait cycle the sole construction is restored to a condition suitable for absorption and storage of the impact energy of the next heel strike event thereupon. Included within the sole construction is a control system which is responsive to the changing anatomy of the foot during the gait cycle and which control system manages the timing of the transfer of the absorbed and stored heel strike energy to the forefoot.
