1. A golf club head, comprising:

  • a crown defining an upper surface of the golf club head;

    a sole defining a lower surface of the golf club head, comprising a transmittal portion, a flexure and a rear portion;

    a side wall extending between the crown and the sole;

    a hosel extending from the crown and including a shaft bore; and

    a face defining a ball-striking surface and intersecting the transmittal portion at a leading edge, wherein the face includes a face insert that forms at least a portion of the ball-striking surface, wherein the face insert is constructed of maraging steel and has a thickness less than 2.0 mm,wherein the flexure is spaced aftward of the ball-striking surface by the transmittal portion, and comprises a front wall, an apex and a rear wall, wherein the front wall extends into a cavity defined by the golf club head and the rear wall extends into the cavity, and the front wall and the rear wall are coupled at the apex,wherein the flexure is spaced from the ball-striking surface by a distance that is between 20% and 50% of a CG-Z-fc distance between the geometric face center of the golf club head and the center of gravity of the golf club head along a horizontal Z-axis that extends from the face to the aft of the golf club head,wherein the front wall and the rear wall form convergent flanges that are angled toward each other as they extend further toward the interior from the sole so that the fore/aft distance between the members decreases from the lowest portion, when the golf club head is in the address position, to the most inward, upper ends.
