The Callaway Fusion Wide Sole irons are a super-premium iron loaded with high-performance technology. Utilising Callaway Golf's revolutionary weight-shifting science of Fusion Technology, Callaway Golf club designers and engineers have packed everything they currently know about game-improvement clubs into the Fusion Wide Sole Irons. The Callaway Fusion Wide Sole clubhead is made of 6-4 titanium and is 25 percent larger than the original Fusion Iron clubhead.

The Callaway Fusion Wide Sole irons have a larger effective hitting area, higher stability and increased offset for enhanced confidence. TuniteT, Callaway Golf's proprietary, ultra-dense alloy developed for the original Fusion Irons, is fused to the bottom of the body, dramatically lowering the centre of gravity for greater forgiveness and aid in launching the ball up quickly and easily. The sole's wide design instills more confidence and helps the clubhead glide smoothly through turf while limiting digging on miss-hit shots. Contributing to the solid feel of the Fusion Wide Sole Irons is the unique TPU SenSert insert in the back cavity. The TPU SenSert insert is a chemically engineered thermoplastic polyurethane that decreases vibration for consistent feel on every shot.
