Abstract
A midsole assembly for an athletic shoe includes a midsole formed of soft elastic material, a corrugated sheet interposed in the heel portion of the midsole, a plurality of transverse holes formed at the contact regions of the midsole with the corrugated sheet, and through holes extending vertically and communicating with transverse holes. In using this shoe, air flows into the shoe through the transverse holes and the through holes. Thus, good ventilation can be acquired especially at the heel portion of the inside of the shoe. The corrugated sheet maintains the shape of the transverse holes and prevents them from being crushed by the impact load applied onto the midsole at the time of impacting the ground so that ventilation can be secured in a highly loaded athletic shoe.
