In a sole which is attached to a ground contact region of an athletic prosthetic leg which has a leaf-spring-like leg portion extending to a side of a toe via at least one curved portion, the ground contact region extending from the toe to a side of the curved portion in an arc, the sole includes a bottom surface having a shape conforming to an extending shape of the ground contact region, and, in the bottom surface, a region at the side of the curved portion, which is defined by a border as a line extending in a width direction of the leg portion through a contact point with a road surface in a standing state of a wearer who wears the athletic prosthetic leg, has a higher drainage performance compared with a region other than the region at the side of the curved portion.
