Abstract
A shoe sole structure includes an outsole that extends from a heel region to a forefoot region of a shoe, and a midsole that is disposed above the outsole and extends from the heel region to a midfoot region of the shoe. A heel portion of the outsole includes a corrugated portion. A heel portion of the midsole includes a corrugated portion, which corresponds in phase to the corrugated portion of the outsole. Cleats are provided at a bottom surface of the outsole. The corrugated portion on the outsole provides running stability. 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.
