Hot Launch C523 wedges combine maximum distance and forgiveness in a traditional cavity back design. The C523 Irons are made from extremely soft 431 stainless steel, providing a superior feel and performance.VIBRCOR TECHNOLOGYVIBRCOR is a high-grade TPU strategically placed in the deep undercut pocket to create a new speed-inducing and feel-enhancing internal technology. VIBRACOR creates a distinct feel of the clubhead at impact that dampens sound and shock, while also creating perimeter weighting around the entire clubhead for maximum forgiveness and power and ball speed enhancement off the face.COMPACT DESIGN FOR SHARPER HIGH TOEA new shape for the C523 Wedge features a more compact design, a thinner topline, and a sharper high toe that promotes myriad game-improvement benefits in a classic iron. The more compact design of the C523 Wedge has removed weight from the top line to create an ultra-low CG. The ultra-low CG placement promotes a high launch, stability at impact, and added forgiveness on off-center hits.WIDE SOLE/DEEP UNDERCUT DESIGNThe wide sole of the C523 Wedge and its deep 360-degree undercut cavity is optimized for playability, turf interaction and ease of launch. The wider sole of the C523 offers superior bounce and increase launch for clearer, high-flying shots. The wider sole design leads to cleaner turf interaction for more consistent shot making. The 360* undercut cavity creates more face flexing and faster ball speed across the entire face.TOE WEIGHTED DESIGNAdvanced toe weighting has strategically increased and made more visible in the new C523 Wedge design. This added toe weighting maximizes stability on impact and provides a better off-center hit distance from the face of the iron and elongates the sweet spot and creates a pure feel off the face of the irons.POWER LOFTED SETUPThe lower and deeper CG allowed the C523 wedges to be power lofted to
