Abstract: A shoe sole of the present invention includes a first member 10 including a first deformable portion 11, and a second member 20 including a second deformable portion 21. In a non-worn state, a first lower surface 10d of the first deformable portion 11 and a second upper surface 20u of the second deformable portion 21 are substantially spaced apart from each other in a vertical direction. Under a first load, the first deformable portion 11 deflects downward, whereby the first lower surface 10d can approach the second upper surface 20u until the first lower surface 10d contacts the second upper surface 20u. Under a second load, the deformable portions 11 and 21 both deflect downward with the engagement elements 12 and 22 of the deformable portions 11 and 21 engaging with each other.

Abstract: A low rigidity region being more stretchable and bendable than a high rigidity region, includes a main portion, and a medial first flexible portion and a lateral first flexible portion extending from the main portion in the medial and lateral directions. The main portion covers a portion of the area from the shaft of the first proximal phalanx to the shaft of the second proximal phalanx, the medial first flexible portion covers a portion of the area from the shaft of the first proximal phalanx to the head of the first metatarsal bone, and the lateral first flexible portion extends to the lateral side of the foot from the main portion. When pushing off the foot onto the medial/lateral side in a diagonally forward direction, the upper bends along the diagonal bend lines. Therefore, the diagonal portions and the main portion serve as the bend lines.

Abstract: An athletic shoe suitable for efficient running. A depression is formed in the rear foot portion which extends forward from the calcaneal bone and which does not contact the ground. A band-like area is provided in the middle foot portion extending in the front-rear direction in the central portion between the medial side and the lateral side of the shoe sole so as to be continuous with the depression. The reinforcement member and the midsole are provided in the middle foot portion so that the upper surface of the midsole less easily sinks downward due to a load from above on the medial side than in the band-like area and on the lateral side. In the front foot portion, a longitudinal groove is formed which extends in the front-rear direction in the central portion of the midsole body so as to be continuous with the band-like area. The longitudinal groove is curved so as to be generally parallel to the lateral edge of the front foot portion of sole.
