The Nike Slingshot 4D irons add progressive change to four critical areas of performance to create irons that play how you need them to, when you need them to.

#1: Slingback: Design positioned strategically (low and back in long irons; higher and forward in short irons) in each club to achieve the desired ball flight.

#2: Variable Sole Width: Narrows progressively throughout the set (long irons are wider for higher launch; short irons are thinner to provide greater control).

#3: Progressive Offset: 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.

#4: Club Head Profile: The long irons offer hybrid-like forgiveness and high, soft-landing shots. The mid-size profile of the short irons enhances control and accuracy.
