Abstract: Footwear includes a sole portion that supports a foot sole of a foot of a wearer, the sole portion including a ground contact surface and a shock absorbing portion formed of an elastic body. The shock absorbing portion includes a three-dimensional mesh structure portion in which a plurality of unit structures are repeatedly arranged so as to be adjacent to each other and an irregularly shaped portion that has a different shape from each of the unit structures and is at least partially embedded in the three-dimensional mesh structure portion. The irregularly shaped portion includes a protruding plate portion in which a central portion protrudes relative to a peripheral edge portion in a direction orthogonal to the ground contact surface.

Abstract: Footwear includes a footbed portion including a support region. The support region includes an upper surface-side projection portion forming region having a plurality of upper surface-side projection portions. A maximum outer dimension in a cross-section orthogonal to a projecting direction of each of the plurality of upper surface-side projection portions is not greater than 3.0 mm. A projection length of each of the plurality of upper surface-side projection portions is not less than 4.0 mm and not greater than 13.0 mm, and an arrangement density of the plurality of upper surface-side projection portions in the upper surface-side projection portion forming region is not less than 10% and not greater than 100% in terms of an area ratio. An elastic modulus of a material forming the plurality of upper surface-side projection portions is not less than 0.1 MPa and not greater than 100 MPa.

Abstract: Footwear includes a shell including an outsole portion; and a sole body including a footbed portion. The footbed portion includes a shock absorbing portion formed of a three-dimensional mesh structure body so as to extend to a peripheral surface of the footbed portion. An engaged portion is disposed in an inner side surface of the outsole portion, and an engaging portion is disposed in a portion of the shock absorbing portion that corresponds to the peripheral surface. One of the engaged portion and the engaging portion is a protruding portion while the other one of the engaged portion and the engaging portion is a cutout portion provided as a recessed portion or a hole portion. An occupied volume ratio of a region including at least a portion defining the engaging portion in the shock absorbing portion is locally increased.
