Slingshot 4D irons add progressive change to four critical areas of performance to create irns that ho you need then to, when you need them to.
Design postional strategically (low and back in long Irons; higher and forward in short irons) in each club to achieve the desired ball flight.
Narrows progressively throughout the set (long irons are wider for higher launch; short irons are thinner to provide greater control).
Offset in the long irons make it easier to square the face and hit high, straight shots. Incremental decreases in the mid and short irons ensure precise shot-making with the scoring clubs.
The long irons offer hybrid-like forgiveness and high soft-landing shits. The mid-size profile of the short irons enhances and accuracy.
