wherein a ratio of a moment of inertia about a golf club head center of gravity x-axis (Ixx) generally parallel to the head origin x-axis to the volume of the club head is greater than 0.665 kg/m and Ixx is as at least 310 kg-mm2;
wherein Zup is no more than 30 mm, where Zup is defined as the location of the center of gravity in the z-axis direction from the ground plane to the center of gravity when the club head is in the normal address position;
wherein the face has a face area of no more than 4600 mm2;
wherein a mass of the club head is no more than 205 grams;
wherein the sole is convex;
wherein the sole further comprises a raised sole portion and a non-raised sole portion, wherein the raised sole portion is convex,wherein the raised sole portion is raised toward the top side producing a recess on the lower side, and wherein the raised sole portion has a smaller radius of curvature than the non-raised sole portion;
wherein the raised sole portion comprises a forward portion, and the forward portion of the raised sole portion is located proximate to the weight port and forward of the weight port and extends from at least a location located heel-ward of the y-axis to a location located toe-ward of the y-axis; and
wherein the club head has a forgiveness ratio that is at least 0.915, wherein the forgiveness ratio is defined as (hosel axis to back dimension)*(face area)/(volume).

Abstract
Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.
