A sole structure of a shoe includes a rearfoot-side concave-shaped portion including a vertex region in a bottom surface of the sole in a rearfoot region. The vertex region is positioned at a highest position within the bottom surface of the sole in the rearfoot region and configured to be positioned at a position corresponding to a center of a heel of a wearer such that center of pressure of the wearer overlaps with the center of the heel.

An upper includes an upper body covering the instep of a foot. An upper body includes a first layer, a second layer disposed with a gap from the first layer, and a third layer connecting the first layer and the second layer. A part of the upper body is disposed with a low stiffness region having lower stiffness than an adjacent region. At least a part of the low stiffness region has a point in which the third layer is not disposed. A plurality of holes is disposed in at least a part of a portion of the first layer and the second layer of the low stiffness region corresponding to the point in which the third layer is not disposed.

Upper and shoe including the same

A shoeincludes a twist allowance partand a medial reinforcement member(bend restraining part). The twist allowance partis provided in a medial part of a midfoot portion in a shoe soleserving as a bottom portion and allows medial twisting of the heel side with respect to the toe side. The medial reinforcement memberis disposed on the twist allowance partand restrains upward bending of the heel side in the medial part.

Shoe

A shoe sole includes a body portion and a heel holding portion. The heel holding portion is located opposite to a ground contact surface of the body portion and holds a heel portion of a foot at least from a medial foot side. The body portion includes a low hardness portion and a high hardness portion. The high hardness portion is a foam material harder than a foam material of the low hardness portion. The heel holding portion is a resin harder than the foam material of the low hardness portion and the foam material of the high hardness portion. On the medial foot side in a rear foot portion, the low hardness portion is located between the heel holding portion and the high hardness portion in an up-down direction.

Shoe sole and 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

A sole of a shoe includes a forefoot support portion Rthat supports a forefoot of a foot of a wearer, a midfoot support portion that supports a midfoot of the foot of the wearer, and a rearfoot support portion that supports a rearfoot of the foot of the wearer, which are connected in order from a front side toward a rear side. A ground contact portion having a portion positioned on a lowermost line connecting a lowermost point of the forefoot support portion and a lowermost point of the rearfoot support portion in a side view is formed in a medial-foot-side region of a bottom surface of the midfoot support portion. A protrusion protruding toward the medial foot side is formed on a medial-foot-side side surface of the midfoot support portion.

Sole of shoe and shoe

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

Shoe sole

An upper includes an upper main body that covers an instep of a foot. The upper main body includes: a first portion including a plurality of linear bodies and formed by one layer; and a bag-shaped second portion formed by two layers in which some of the plurality of linear bodies constituting the first portion serve as one layer and the rest of the plurality of linear bodies serves as another layer. Inside the second portion, a cushioning material is put. The second portion protrudes toward a foot of a wearer with respect to the first portion.

Upper and shoe

An upper includes an upper main body that covers an instep of a foot. A first region and a second region adjacent to the first region are formed in the upper main body. The upper main body includes: a first linear body provided across the first region and the second region or provided only in the second region; and a second linear body provided in the first region while avoiding the second region and having an end located at a boundary portion between the first region and the second region. The first linear body and the second linear body have mutually different stretchability.

A shoe is provided with a first forming portion provided on a medial side and a second forming portion provided on a lateral side across a central opening formed forward from a foot insertion portion of an upper on each of which a string passing portion is formed; a first support member a tip end of which is fixed to the second forming portion, including a first string passing structure provided at the tip end, and extending downward so as to abut a medial side of a foot; a second support member a tip end of which is fixed to the first forming portion, including a second string passing structure provided at the tip end, and extending downward so as to abut a lateral side of the foot; and a shoelace which passes through the string passing portion and continuously passes through the first and second string passing structures.

A low rigidity region being more stretchable and bendable than a high rigidity region, includes a main portion, and a medial first flexible portion and a lateral first flexible portion extending from the main portion in the medial and lateral directions. The main portion covers a portion of the area from the shaft of the first proximal phalanx to the shaft of the second proximal phalanx, the medial first flexible portion covers a portion of the area from the shaft of the first proximal phalanx to the head of the first metatarsal bone, and the lateral first flexible portion extends to the lateral side of the foot from the main portion. When pushing off the foot onto the medial/lateral side in a diagonally forward direction, the upper bends along the diagonal bend lines. Therefore, the diagonal portions and the main portion serve as the bend lines.
