Abstract
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.
