The shoeincludes the outer solebrought in contact with the road surface, the midsolearranged on the outer sole, and the uppercovering the foot from the upper side. The midsoleincludes at the middle foot portion the cut-out portionand the like opened to the outside and closed at the middle portion in the width direction.

Shoe

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.

Footwear

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.

A shoe soleincludes a bottom partand a deformation restraining part. The bottom partincludes: a rear bottom surface partformed to extend from a rearfoot to a midfoot portion and to be, when the shoe sole is placed on a virtual surface S as a flat surface, in contact with the virtual surface S; and a toe portionof which a height from the virtual surface S is set to 100% or greater and 250% or less with respect to a thickness in the rear bottom surface part. The deformation restraining partis disposed in an edge part on a medial side and a lateral side of the bottom partand extends from a forefoot to the midfoot portion along the bottom part. The deformation restraining parthas higher hardness than the bottom part

A plate includes: a curved portion located in a forefoot region and shaped to curve toward a flat plane; a midfoot supporting portion located in a midfoot region; and a rear-foot supporting portion located in a rear foot region. The curved portion has a wide region including a wide portion of which dimension in a width direction is largest in the curved portion. The midfoot supporting portion has a narrow region including a narrow portion of which dimension in the width direction is smallest in the midfoot supporting portion. A ratio of a bending rigidity of the narrow region to a bending rigidity of the wide region is 0.4 or more and 0.85 or less.
