ABSTRACT:
A sole configuration for a golf club head that provides the benefits of a sole configuration incorporating a medial ridge design. The medial ridge divides the sole into a toe and heel section. The sole further comprises a first and a second recess in the toe and heel sections respectively, wherein the first and second recesses are downwardly convex thereby allowing for the center of gravity of the golf club head to be positioned lower than in a golf club head having recesses that are downwardly concave. The first recess has a horizontal concavity that is in an opposite direction from the concavity of the second recess.
