E523 WEDGE Houdini Sole is a raised steel mass area at the rear of the clubhead, as well as a curved leading edge under the face. The patented sole design reduces the amount of sole area to reduce drag and turf interaction by 35% and is instrumental in significantly altering the CG placement of the E523 Wedge. The wide sole of this super game improvement wedge has been condensed in the 523 Series while still providing all the benefits of a wide sole design wedge. Extra camber has also been added to the sole of the clubhead. The wide sole and heavier weight of the E523 Wedge provide superior contact through the turf and help eliminate flubs, while the additional camber reduces digging. This extremely deep undercut cavity dramatically lowers the CG for the ultimate in wedge forgiveness. It redistributes mass for enhanced flight control and to create a higher launch with increased spin for extreme playability from the sand and rough. An oversized face design on the E Series wedge provides more striking area for players seeking an extreme game improvement wedge. The E523 wedge design enhances consistency and accuracy. It also raises the Moment of Inertia for enhanced precision around greens and better playability from the sand and rough. The full-face coverage grooves of the E523 Wedge are maximized to USGA depth and sharpness. The groove design provides exceptional spin and control across the entire face of the wedge.
