An object of the present invention is to provide a sole of a baseball spike shoe that improves a ball speed in a pitching motion. A sole includes a plurality of first protrusions arranged in a forefoot region of a sole body. Each of the first protrusions is formed such that its longitudinal direction extends along a foot width direction in a bottom view. When the plurality of first protrusions are projected on a virtual projection plane as viewed from a front side of the sole body, the sum of projection lengths of the plurality of first protrusions in the foot width direction is 85% or more and 100% or less of a distance of a straight line connecting in the foot width direction a side of the most medial first protrusion to a side of the most lateral first protrusion.

Sole and baseball spike shoe with the sole

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.

Sole structure for a shoe

A support is configured such that a bulge is allowed to deform toward a deformation space due to the deformation space when the deformation space is in an open state, and that the bulge is allowed to deform upward and a buffer member is compressively deformed when the deformation space is in a closed state.

Sole structure and shoe including same

A sole structure includes an outsole having a ground surface as a lower surface; a midsole stacked on a top of the outsole and made of an elastic material; and a supporter provided around a middle of the midsole in a thickness direction, and extending longitudinally to include a heel region corresponding to a heel of a foot. The supporter includes a base provided in a central region of the heel region in a foot width direction, and a corrugated side provided continuously with each side of the base in the foot width direction, and including a ridge with its apex located above the base, and a groove provided continuously with a rear of the ridge with its bottom located below the base at the rear of the heel region.

Sole structure for shoes and shoe with the sole structure

A sole structure for a shoe that can reduce the burden of MP joints and a knee joint of a shoe wearer's foot during running and that can improve cushioning properties. The sole structure of the shoe includes an upper plate of a hard elastic member disposed at a forefoot region of the shoe, a lower plate of a hard elastic member disposed under and spaced away from the upper plate, and a midsole of a soft elastic member interposed between the upper plate and the lower plate. The midsole has a longitudinally extending hollow portion that is upwardly concavely curved at a lateral mid-portion of the midsole. The lower plate has a concave portion corresponding to the hollow portion of the midsole.
