SOLUTION: A fitting hole having a shape coinciding with the shape of the bottom surface of an ankle lower 30 is formed to the bottom surface of a first cushion member 50 and the insertion part 54 into which the ankle lower is inserted is formed so as to communicate with the fitting hole. The cushion member 50 allows the leading end part of the ankle lower front part 32 to reach the front foot part of the fitting hole through an insertion part 54 and, next, the ankle lower rear part 33 is allowed to reach the ankle side of the fitting hole through the insersion part 54. A through-hole 512 piercing the fitting hole from the upper surface 511 of the front foot side cushion part 51 of the cushion member 50 is formed and a columnar ankle bamper 513 coinciding with the shape of the through-hole 512 is fitted in the through-hole 512. A semi- columnar heel bamper 523 conciding with an ankle side is fitted to the ankle side of the housing part 54 of the cushion member 50.
