Abstract
A compliant golf club head permits a more efficient impact between a golf ball and the golf club head. By allowing a face section of the golf club head to flex rearwardly during impact with the golf ball internal stresses within the golf ball are reduced to yield a more efficient impact. A thin wall section is located generally parallel with the face and near the junction with a top, bottom heel and toe sections to allow the face of the golf club head to flex rearwardly.
