Nike Slingshot 4D Irons with Steel Shafts: Shift your center of gravity with the latest irons from Nike Golf SlingShot irons feature Air Center of Gravity (CG). Unlike conventional irons, the CG of the SlingShots is suspended in the air beyond the face thickness. As a result, the ball launches higher and it's easier to square the club face -- thanks to 455 stainless steel that's lighter, yet stronger and faster.  

The Nike Slingshot 4D irons has achieved great improvement on the four critical areas of performance to create irons that the golf player can rely on. Slingback: Design positioned weight stategically (low and back in long irons; higher and forward in short irons) in each club to achieve the desired ball flight Variable Sole Width: Sole width narrows progressvely throughout the set — long irons are wider for higher launch; short irons are thinner to provide greater control

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

Variable Sole Width: Sole width narrows progressvely throughout the set — long irons are wider for higher launch; short irons are thinner to provide greater control

clubs 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
