Abstract
A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball; an elongated channel extending across a portion of the sole, wherein the sole is made of a plurality of materials where one material has a lower modulus of elasticity than the remainder of the sole. The sole has an elongated channel recessed from adjacent surfaces of the sole and may be made entirely or partially from a material with a lower modulus of material than the remainder of the sole. The flexibility of the elongated channel and lower modulus material helps to improve the efficiency of the impact with a golf ball.
