Abstract: An improved resilient shoe sole includes an outsole having a substantially inelastic side wall with a heel cavity. A substantially inelastic platform is located below the heel cavity, and a connector connects the platform with the side wall. The connector has a particular length and thickness to maintain the platform substantially below the sidewall when the shoe sole is not under a wearer's weight. When brought under forces of a wearer's weight, the connector bends and stretches as the spring compresses to allow the platform to deflect into the heel cavity. As weight is removed, the connector and spring cause the platform to deflect out of the heel cavity, biasing the platform below the side wall.

Abstract: 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.

Abstract: An improved shoe includes an apparatus and system for ventilating inside the shoe and a resilient shoe. External air desirably enters the shoe around the wearer's foot and flows through holes in the sole into aeration chambers. The air circulates to the heel by a suction valve and is controllably directed out to the exterior of the shoe through a one-air air exhaust valve, ventilating the wearer's foot while an individual is walking. The heel is made from a resilient material and has a cavity extending under the entire instep portion of the shoe's upper. Compression springs are placed in the cavity, including a mainspring located at approximately the heelstrike point and two auxiliary springs for stability located forward of the mainspring toward the shoe's toe. The action of the springs is distributed throughout the sole by a resilient layer of softer rubber adjacent the sole to provide for a resilient walking experience.
