ABSTRACT:
An undamped spring having multi-spring rates is provided in the heel support portion of a shoe for resiliently compressing under heel pressure against the ground and returning a substantial portion of the energy of the pressure to the wearer's foot. The spring is formed of upper and lower leaf-like legs which are integrally joined together at an acute angle whose apex is directed forwardly relative to the shoe. An intermediate leaf-like leg is located between and integrally joined with one and extended towards the other of the upper and lower legs. Thus, heel pressure compresses the upper leg towards the lower leg until the intermediate leg is engaged and, thereafter, spring compression continues at an increased spring rate.
