Abstract
A shoe sole comprises an outsole having a recess formed in the upper surface and an insert formed of resilient material that fits in the recess. The insert has a plurality of longitudinally spaced, downwardly extending transverse ribs extending across the underside of the insert. The ribs are formed of at least two lengths, with longer ribs alternating with shorter ribs in a regular pattern along the longitudinal length of the insert. The ribs are formed in a wavy sinusoidal pattern across the width of the shoe and the individual ribs are formed in sinusoidal vertical patterns, so that each individual rib has downwardly extending portions of different lengths that repeat in a pattern across the width of the shoe. The varying lengths of the ribs provide a first cushioning rate for initial compression of the insert, while the shorter portion of the ribs provide a graduated increase in spring resistance upon further compression of the ribs.
