Golf club with improved sole geometry

Abstract

In one or more arrangements, a golf club head having improved sole geometry is provided. The golf club head includes a striking face portion located at a frontal portion of the golf club head, a topline located at an upper portion of the golf club head, a heel portion located at a proximal end of the golf club head, a toe portion located at a distal end of the golf club head opposite the heel portion, and a sole located at a lower portion of the golf club head. The golf club head is adapted to receive a shaft. The golf club has a cross section having a sole width less than 15 mm and a camber area percentage greater than 40% (and in some arrangements greater than or equal to approximately 59%). In some arrangements, the cross section additionally exhibits trailing edge relief.
