Abstract: The present invention pertains to a resilient shoe insole. The shoe insole is comprised of a resilient material having sufficient thickness in the heel and forefoot region to allow the resilient material to act as a spring, thereby absorbing the impact of a foot and then returning at least 70% of absorbed energy to the foot thereon and providing increased lift and response to the foot and reduced O.sub.2 demand in running relative to other insoles for a given activity. In a preferred embodiment, the shoe insole has a heel portion and a forefoot portion, wherein the heel portion is thicker than the forefoot portion. The heel portion is at least 3/8 inch thick and the forefoot portion is at least 1/4 inch thick. In another embodiment, the base is comprised of multiple laminations of the resilient material.
