The upper U has a first opening 1 from which a leg extends upwardly during wearing and a second opening 2 which is closed with a tongue, and the first and second openings 1, 2 are continuous with each other in a front-rear direction, the upper comprises a medial side portion 7 covering a medial side surface of the foot, a lateral side portion 8 covering a lateral side surface of the foot, and stretchable portions 71, 81 forming a part of the medial side portion 7 and/or the lateral side portion 8, and the second opening 2 inclines toward the medial side of the foot along a ridge line of the foot as the second opening extends toward a front of the foot.

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: Disclosed is a shoe sole comprising an outer sole 1F, 1B, a midsole 2 and a reinforcement device 4 made of a resin plate. The reinforcement device 4 is firmly secured to the underside of an arch portion 2M of the midsole 2. At a medial side 11 and a lateral side 10 of the foot, the reinforcement device 4 is shaped like an arch between separated outer sole parts 1F and 1B. A medial foot portion 43 of the reinforcement device 4 is formed to have a higher hardness than a lateral foot portion 40 of the reinforcement device 4. This allows the reinforcement device 4 to have a greater flexural rigidity in its medial foot portion 43 than in its lateral foot portion 40.
