Abstract
An athletic shoe with an energy return system is provided. The shoe includes a shoe sole assembly having a midsole, at least one stabilizer plug in a recess in the midsole, and at least one outsole member. In an aspect, the stabilizer plug has at least one trampoline recess disposed in an upper surface thereof, and at least one projection extending from a lower surface thereof that substantially underlies at least a portion of the at least one trampoline recess. An upper surface of the outsole is adapted to complimentarily receive the at least one projection extending from the lower stabilizer plug surface such that when a force is applied to the lower outsole surface during a foot strike, the at least one trampoline recess receives underlying portions of the stabilizer plug to accommodate elastic deflection of the underlying portions of the stabilizer plug and the outsole.
