Foamed shoe sole

Abstract

A foamed sole body includes a front portion, a heel portion, an intermediate portion interconnecting the front, and heel portions, and a peripheral surface that surrounds the front, intermediate and heel portions and that interconnects top and bottom surfaces of the sole body. An outer covering layer is bonded to and covers entirely the peripheral surface of the sole body. Alternatively, the outer covering layer may cover not only to the bottom surface of the sole body but also the peripheral surface.
