The Nike Slingshot Tour irons are for players who prefer a classic iron profile packed with modern technology. Contrary to the original Slingshot and Slingshot OSS irons, the distinctive Slingback design in the Nike Slingshot Tour irons is not as visible in the playing position. This shallower Slingback design along with minimal offset, allows for more shot-shaping creativity. The Nike Slingshot Tour irons are more traditional irons featuring a Custom 455 face material with a thinner top-line. To enhance feel, the Slingshot Tour irons' body is made of 431 stainless steel which is 25% softer than the more commonly used 17-4 stainless steel. These irons come with Dynamic Gold Shafts by True Temper.
