Abstract
An integrally molded midsole for an athletic shoe having tubular suspension members is disclosed. The tubular suspension members behave as springs and have spring constants which may be designed for a particular application by choice of the tube length, the tube wall thickness or the hardness of the tube material. Preferably, the midsole is made of an elastomer such as HYTREL that is cast in a preformed shape and thereafter subjected to substantial compressive forces so that the tubular springs take a compression set and thereafter perform as near-ideal springs.
