ABSTRACT:
The present invention is directed to a method of manufacturing a midsole for a shoe and the structure of the resulting midsole. The midsole includes a core of a first plastic material and a peripheral wrap of a second plastic material. The wrap has an outer peripheral surface comprising at least a portion of an outer peripheral surface of the midsole. The method includes the steps of molding a peripheral wrap from a sheet stock of the first plastic material by applying compressive forces on the sheet stock in a direction which is substantially perpendicular with the outer surface of the sheet stock, placing the wrap around the inner peripheral surface of a mold which approximates the shape of the midsole, and pouring the first plastic material in the mold.
