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.
