1. A shoe sole comprising: a sole member having a first layer of material overlying a second layer of material, the first and second layers of material including opposing first and second surfaces, respectively, wherein the second surface of the first layer of material is continuously attached to the first surface of the second layer of material along at least a portion of a length of the first surface; the second surface of the second layer of material including a plurality of lugs arranged in a substantially sinusoidal wave pattern along a longitudinal axis of the sole, at least one of the plurality of lugs having a crest, wherein an axis extends transverse to the longitudinal axis through the crest, and the first and second layers of material, at least at the axis, form a solid body with the first layer of material being harder than the second layer of material; the second surface of the second layer of material being either: (1) an outermost layer of the sole without another layer of material overlying it, wherein the outermost layer is positioned so as to contact the ground once the sole is incorporated into a shoe; or (2) engaged to an outsole along at least a certain length of the second surface, a combination of the outsole and the second layer of material forming a substantially sinusoidal wave pattern that is positioned so as to contact the ground once the sole is incorporated into a shoe.
