Each layer has an upper contoured surface such that the total compressibility of the shoe bottom, as determined by the relative thicknesses of the layers, is predetermined and differs along the surface. The upper layer has an uppermost surface (4) which is shaped to fit against and be complemental to the bottom of the foot of a wearer.</p> |
