Abstract
A sole unit for footwear such as an athletic shoe includes an integral midsole/wedge or a wedge for use with a midsole. The integral midsole/wedge unit and the wedge for use with a midsole both are formed by a shell and an encapsulated core. The shell and core comprise plastic materials which have individual strengths and weaknesses in a shoe construction, yet provide, as a composite improved results in a shock dispersion and memory system. In a second aspect, the integral midsole/wedge is a single density or a two-density unit precompressed from a low density material.
