A new, super-premium iron that utilizes Fusion Technology — the innovative weight distribution technology created by Callaway Golf — the Fusion Wide Sole Irons use advanced multi-material design to create an oversized game-improvement iron.

Three distinct materials are brought together to create the Fusion Wide Sole Irons: 1. A dense alloy, Tunite, is fused into the sole, optimally placing the CG low in the clubhead to help get the ball in the air quickly and easily. 2. Lightweight 6-4 titanium is used to form the body. 3. A special vibration-dampening TPU SenSert insert is used in the back cavity, resulting in exceptional feel on every shot. 4. Lightweight 6-4 Titanium Body5. Titanium body is 35% lighter than a comparable steel body, allowing Callaway Golf engineers to create an oversize clubhead with increased offset for greater forgiveness, an increased effective hitting area and more confidence.

Heavy Tunite weighting in the sole of the clubhead dramatically lowers the CG to help get the ball in the air quickly and easily. The SenSert is composed of a chemically engineered thermoplastic urethane that decreases vibration and creates an incredibly solid feel. The wide sole design instills confidence and helps each iron in the set glide smoothly and easily through the turf.

Following on the success of its Fusion Irons, Callaway has introduced the Fusion Wide Sole. The Wide Sole takes the technology of the Fusion Irons and applies it to an oversized game improvement iron.

I liked the Fusions when I tried them—although unconventional in design, at address they looked very good. They also had a good feel and trajectory.

The major change in the design is the larger head and the—obviously—wider soles, into which Callaway has inserted “Tunite” weights to further lower the center of gravity. The new clubhead is 25% larger than the original.

Like the original Fusion Irons, the clubhead is constructed from a 6-4 titanium body into which a special vibration dampening material has been injected into the back cavity.  The TPU SenSert™ insert is a chemically engineered thermoplastic polyurethane. It looks funky, but you can’t argue with the results.

I think Callaway deserves props for thinking outside the box on these clubs. This is a set I’d like to give an extended test run to.
