A stud for an outsole includes: an outer tubular portion located on an outsole body and having a tubular shape; and a core portion located inside the outer tubular portion. The outer tubular portion is integral with the outsole body with no seam between the outer tubular portion and the outsole body. An inner wall surface of the outer tubular portion surrounds, and is in contact with, a side surface of the core portion. This configuration reduces separation of the stud from the outsole and firmly holds the stud on the outsole.

A sole structure for a shoe includes an upper wall portion disposed on the upper side, a lower wall portion disposed below and away from the upper wall portion, and a sidewall portion that is disposed between the upper wall portion and the lower wall portion and that is elastically deformable in the vertical direction. The upper and lower wall portions and the sidewall portion are formed of resin-made wall-shaped members. A three-dimensional elastic fiber structure formed of resin fibers is provided in the interior region between the upper wall portion and the lower wall portion. The interior region includes a hollow portion that is in contact with the three-dimensional elastic fiber structure via a partition wall formed of a resin-made wall-shaped member.

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.
