Abstract: A four faceted sole for a high performance, large volume golf club head is disclosed herein. The sole has a central facet, a heel facet, a toe facet and a rear facet. The central facet occupies 50 to 70 percent of the total sole surface area. The toe facet, the heel facet and the rear facet are all preferably angled relative to the central facet. The four faceted sole allows for a lower center of gravity for the golf club head and a specific moment of inertia.
