When a region on which the grid-form rib is provided is defined as a rib region, an additional rib is further provided on the rib region. The additional rib is positioned on a heel side relative to a face center. Preferably, the grid-form rib is formed by intersection of first ribs extending in a substantially toe-heel direction and second ribs extending in a substantially face-back direction. Preferably, the additional rib is sloped to be closer to a back side as approaching to the heel side.
