Abstract
An athletic shoe sole structure includes a midsole body that extends from a heel region to a forefoot region of a shoe, and an outsole body that is disposed under the midsole body, extends from the heel region to the forefoot region of the shoe, and is formed of a harder material than the midsole body. A heel portion of the outsole body includes a corrugation. The sole structure further includes a lower midsole disposed under the heel portion of the outsole body, an outsole heel portion attached at a lower surface of the lower midsole, and cleats provided at a lower surface of the outsole body. The sole structure having only two layers with the outsole and the midsole decreases the weight of the shoe, simplifies a manufacturing process, and reduces a manufacturing cost.
