The rear side of the air pipe(120) is connected to the inner space of the heel and the front side is connected to an air circulating hole(122) through which the air flows in and out. The spring member(142) is inserted at a predetermined location in the upper direction. The simulating protrusion(140) is exposed in the upper direction. The midsole has a certain thickness and is inclined downward in the width direction. |
