Patent

CA 2311593

A midsole assembly for an athletic shoe comprises a midsole 3 formed of soft elastic material, a corrugated sheet 4 interposed in the heel portion of the midsole 3, a plurality of transverse holes 6, 7 formed at the contact regions of the midsole 3 with the corrugated sheet 4, and through holes 10, 11 extending vertically and communicating with the transverse holes 6, 7. In using this shoe, air flows into the shoe through the transverse holes 6, 7 and the through holes 10, 11, and thus, good ventilation can be acquired especially at the heel portion of the inside of the shoe. Moreover, because the shape of the transverse holes 10, 11 is maintained by the action of the corrugated sheet 4, the transverse holes 6, 7 can be prevented from being crushed by the impact load applied onto the midsole 3 at the time of impacting the ground. In such a way, ventilation can be secured in an athletic shoe as well.
