All of the new Zenergy grips include SuperStroke's new Spyne Technology. �Spyne consists of a heavily embossed ridge along the underside of the grip that guides golfers to a repeatable hand placement. �Consequently, it is significantly easier to square the face at impact and make a more consistent stroke, leading to putts that start online.
