Unlike traditional wedges whose sweet spot is close to the heel, the new Mizuno ES21 Wedges have a centrally located sweet spot, which helps you strike the ball more squarely and generates increased, yet predictable spin. Mizuno achieved this feat by starting with a hollow design, allowing their engineers to remove weight from the heel and push it towards the toe. Then, they elevated the toe slightly, resulting in centrally located center or gravity.The ES21's Quad-Cut Grooves are created using ultra precise CNC milling to boost spin rates even further. Within the grooves you'll find additional Hydroflow Micro Grooves, which are vertically etched to help release moisture and improve wet-weather performance. The ES21 is available with a standard or wide sole.
