Abstract: A sole body has an upper midsole made of an elastic material, staked over an upper side of a lower midsole, and having, on an upper surface thereof, a planta support surface. The upper midsole has a first recess recessed from the planta support surface in a downward direction and having a bottom, and a second recess recessed from a lower surface of the upper midsole toward the planta support surface, and having a bottom. The first and second recesses are alternately and continuously formed in the width direction of the foot.

Abstract: A shock absorbing member includes: support members spaced apart from each other; and a connection member laid across, and connecting together, the support members. Each of the support members includes: an inner wall capable of elastically deforming by external force in a vertical direction; and a first tube and a second tube each provided to one of an outer wall and the inner wall. While inserted through the first and second tubes of the support members, the connection member is integrally formed in a closed shape with ends of the connection member having no seams.

Abstract: A method for producing the shock absorbing member includes: inserting in which each of tubes is housed in a corresponding one of first housings such that molding spaces and the tubes communicate with one another; and molding in which a thermoplastic resin material to form a connection member is heated to melt and injected from a gate toward the molding spaces and the tubes so that the tubes and the connection member are integrally formed.

Abstract: A sole structure includes an upper midsole made of an elastic material and a lower midsole made of an elastic material and bonded from below to the upper midsole. The upper midsole has first protrusions protruding toward the lower midsole, and the tip ends of the first protrusions are in contact with the lower midsole such that the tip ends of the first protrusions can move with respect to the lower midsole.

Abstract: A sole structure includes a plate placed between an outsole and a midsole and disposed at the position corresponding to at least the forefoot and the midfoot of a wearer's foot, and a cushioning body disposed so as to face the sole of the wearer's foot at the position corresponding to the midfoot and the hindfoot of the wearer's foot and capable of absorbing a vertical impact on the upper surface of the cushioning body. The cushioning body and the plate body overlap each other in the vertical direction at the position corresponding to the midfoot of the wearer's foot.

Abstract: A sole structure includes a plate placed between an outsole and a midsole. The plate includes a plate body and first openings. The plate body is made of a material less stretchable than the material of the outsole and is in the form of a thin plate. Each of the first openings extends through a part of the plate body in the vertical direction. The first openings are disposed at a position corresponding to the forefoot and the midfoot on the medial side of a wearer's foot and is covered by the outsole from below.
