Staff Model High Toe ZM Wedge Engineered with a higher toe, full-face grooves, and a wide sole, the Wilson Staff Model ZM High Toe Wedges allow you to manipulate the face and execute every short game shot imaginable. These forged offerings feature Wilson's ZM groove pattern and Garnet Face Blasting technique. This powerful combination of a more frictional surface and deeper grooves extends the time the ball is in contact with the face at impact, resulting in higher and more consistent spin rates
