Abstract: An object of the present invention is to provide shoes with good fitting property. The present invention provides a shoe including: a sole 1 which absorbs landing impact; and an upper 2 which covers an instep of a foot. The upper has a first opening 3 through which the foot is inserted when wearing the shoe. The upper 2 is partly or entirely made of a material which has negative Poisson's ratios.

Abstract: A shoe sole including an outsole 2 and a midsole 1, wherein: the midsole 1 includes a lower midsole 4 of a lower layer formed by a foamed body of a resin, and an upper midsole 3 of an upper layer formed by a foamed body of a resin and arranged on the lower midsole 4; a lateral roll-up portion 42 for supporting a lateral side of a foot from a side of the foot is formed integrally with the lower midsole 4; a hardness of a lateral portion 40 of the lower midsole 4 including the lateral roll-up portion 42 is a first hardness; a hardness of a medial portion 41 of the lower midsole 4 is a second hardness lower than the first hardness; a hardness of a lateral portion 30 of the upper midsole 3 is a third hardness lower than the first hardness; and a part or a whole of the high-hardness lateral roll-up portion 42 is protruding in an upward direction past the upper midsole 3 on a lateral side of the upper midsole 3 so that the lateral side of the foot is supported by the lateral roll-up portion 42 from the side of the

Abstract: An upper including: a cord placed along the longitudinal direction, the cord running through the through holes of the reinforcement members of the medial side portion and/or the lateral side portion; exposed areas in which portions of the cord are placed exposed; and a shoelace engaging with the cord in the exposed areas in a transverse direction of the foot so as to bring the medial side portion and the lateral side portion closer to each other, wherein each of the upper end portions of at least one reinforcement member is attached to the flexible member in one of a fore portion and a rear portion, and is set to be un-attached to the flexible member in the other one of the fore portion and the rear portion.

Abstract: A lace fitting structure for fitting an upper 3 wrapping around an instep of a foot to the instep, the structure including: a medial side portion 31 covering the instep and a medial side surface of a big toe; a lateral side portion 32 covering the instep and a lateral side surface of a little toe; first shoelace means 1 placed to extend in a longitudinal direction Y of the foot and engaged with the medial side portion 31 and the lateral side portion 32 along central edge portions 33 of the medial side portion 31 and the lateral side portion 32; placement means for placing a portion of the first shoelace means 1 so that the first shoelace means 1 is exposed in a plurality of exposed areas 1i, which are separated from one another in the longitudinal direction Y; and second shoelace means 2 engaging, in a transverse direction X of the foot, with the first shoelace means 1 in the plurality of exposed areas 1i so as to bring the medial side portion 31 and the lateral side portion 32 closer to each other, wherein a

Abstract: An upper including: a reinforcement member on a medial or a lateral side being provided, the reinforcement member being less stretchable than a member forming a sock and extending from a medial or lateral eyelet stay to a sole while being attached to a medial or lateral side surface of the sock, the lateral reinforcement member including a first reinforcement portion covering a fifth proximal phalanx from a side surface, and a second reinforcement portion covering a shaft or a base of a fifth metatarsal bone from a side surface, the medial reinforcement member including a third reinforcement portion covering a ball of a big toe from a side surface, and a width of at least one of the reinforcement portions being smaller at a lower end portion thereof than at an upper end portion thereof.
