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.
