US 2001/0039745 A1 · Sole design and structure for athletic shoe

Abstract

A sole structure having an outsole that extends from a heel region to a forefoot region of a shoe and a midsole that is disposed inside the outsole and extends from the heel region to a midfoot region of the shoe. The outsole includes a corrugated portion at a heel portion thereof. The midsole includes a corrugated portion at a heel portion thereof, which corresponds to the corrugated portion of the outsole. A plurality of cleats are provided at a bottom surface of the outsole. Forming the corrugated portion on the outsole makes it possible to secure a running stability. The sole structure having double layers with the outsole and the midsole decreases the weight of the shoe, simplifies a manufacturing process, and reduces a manufacturing cost.
