摘要： 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.

摘要： A golf club head (100) is disclosed. The golf club comprises a ball striking face (102), heel, toe, top ridge (106), and an arcuate bottom sole (108) having a greater ground contact area located adjacent a central portion of a leading edge (114) of the club head that diminishes in size in a heel to toe direction toward a trailing edge of the club head. The club head (100) is further defined by a leading edge (114) being configured with a radius no greater than 50mm approximately midway between the heel and toe to enable the golf club head (100) to enter and penetrate the supporting turf during the execution of a golf shot.
