The invention comprises an improvement in a golf club head of the wood type wherein a sole trough is located so that its root is essentially parallel to the face of the club head and wherein the surface of the trough is flat to convex in planes essentially parallel to the face in a plane through the root of the sole trough and concave in a planes perpendicular to the club face. The purpose of the sole trough is to reduce the cross-section of the club head in cross-sectional planes taken essentially perpendicular to the face of the club head, such cross-sections having a concave surface configuration over the most of the longer dimension of the trough.
