Abstract
An athletic shoe includes an upper, an outsole, a pair of hinged plates, and a spring. The pair of hinged plates are attached between the outsole and the upper in a forefoot portion of the shoe, and the spring biases the plates apart, so that energy is stored and returned during a propulsion phase of a gait cycle in a human step. Foam may be disposed between the plates. A shroud may enclose an outer periphery of the plates. An adjustable torsion spring may be disposed in a hinge portion of the plates, and one or more wave springs may be disposed between the plates.
