Abstract (en)
An improved resilient shoe includes a heel having a cavity extending under the instep portion of the shoe's upper housing compression springs, a mainspring located at approximately the heelstrike point and two auxiliary springs for stability located forward of the mainspring toward the toe. The action of the springs is distributed throughout the sole by a resilient layer of softer rubber in the bottom pad of the heel portion. In an alternate embodiment, the structural walls of the heel portion are configured such that the heel flexes responsive to the forces of the wearer's weight and the captive springs. The shoe is preferably further configured such that external air enters around the wearer's foot and flows through holes in the sole and into the heel, and is controllably directed out to the exterior of the shoe through a one-air air exhaust valve thereby ventilating the wearer's foot while walking.
