To improve gripping force and to realize the smooth movement of the feet in putting the shot.

A first grip part G1 is formed in a range including a thumb part and a thumb globe part on the ground contact surface side of an outsole body 1, and a plurality of grooves M are formed in a range from the front foot part A to the middle foot part B on the ground contact side of the outsole body 1 along a constant pressure line of the foot pressure distribution in putting the shot. The ground contact surface can be reliably gripped by the first grip part in a moment when a pivoting foot kicks in putting the shot and in standing firm with the foot on the opposite side to the pivoting foot. The outsole body can be bent by the grooves H along the constant pressure line of the foot pressure distribution in putting the shot, and therefore, the smooth movement of the feet can be realized according to the foot pressure distribution.
