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.

-20. (canceled)
A golf club head comprising:
- a front end, a rear end, a top side, a lower side, a toe side, a heel side, a hosel positioned at the heel side and defining a hosel axis, a sole positioned at the lower side, a crown positioned at the top side, and an interior cavity, wherein the golf club head has a volume of 350 cm3 to 600 cm3;
- and
- a face positioned at the front end of the golf club head and including a striking surface;
- wherein:
- the striking surface has a club head origin positioned at a geometric center of the striking surface;
- the club head origin defines a head origin coordinate system including:
- a head origin z-axis extending through the head origin in a generally vertical direction relative to a ground plane when the golf club head is in a normal address position, and extending in a positive direction from the club head origin towards the crown of the golf club head;
- a head origin x-axis extending through the head origin in a toe-to-heel direction generally parallel to the striking surface and generally perpendicular to the head origin z-axis, and extending in a positive direction from the club head origin toward the heel side of the golf club head;
- and
- a head origin y-axis extending through the head origin in a front-to-back direction and generally perpendicular to the head origin x-axis and to the head origin z-axis, and extending in a positive direction from the club head origin towards the rear end of the golf club head;
- a golf club head center of gravity z-axis extends generally parallel to the head origin z-axis, and a ratio of a moment of inertia about the golf club head center of gravity z-axis (Izz) to the volume of the golf club head is at least 0.93 kg/m;
- a golf club head center of gravity x-axis extends generally parallel to the head origin x-axis, and a ratio of a moment of inertia about the golf club head center of gravity x-axis (Ixx) to the volume of the golf club head is at least 0.596 kg/m;
- a golf club head center of gravity y-axis extends generally parallel to the head origin y-axis, and a moment of inertia about the golf club head center of gravity y-axis (Iyy) is at least 258 kg-mm2;
- at least 40% of the crown is made of a first fiber-reinforced polymeric material;
- a moment of inertia about the hosel axis is at least 626 kg-mm2;
- and
- Izz is at least 400 kg-mm2, Ixx is at least 270 kg-mm2.
