Abstract
A shoe cushion system integrated in a heel portion of a shoe includes a cavity in the heel of the sole for housing a honeycomb cushion and a strike pad to reduce foot fatigue. A spring is located directly above the strike pad and directs force from the impact of a foot on the heel portion of the shoe. An extendable portion of the spring is positioned within a lasting board aperture, while a flat portion overlaps the lasting board. This spring is made from a gel-like substance, which allows the extendable portion to project through the aperture when force is applied to the heel portion of the shoe. The extendable portion of the spring transfers force onto the strike pad, which in turn presses down on the honeycomb cushion. This honeycomb cushion compresses under the pressure of the strike pad to absorb some of the force.
