Nike Slingshot $D irons. New for 2008 the Nike Slingshot 4D feature the Slingback design that is positioned low and back in long irons and higher & forward in short irons to achieve the desired ball flight. They also feature progressive offset and a variable sole width that progressively narrows throughout the set for greater control. Its new head shape design allows for hybrid-like forgiveness in the long irons, as well as control and accuracy in the midsize profiled short irons.
Slingback design is strategically positioned on each club to achieve optimal trajectory.
Sole width changes to optimize launch angle and shot-shaping ability.
Progressive offset provides more offset in the long irons for straighter, higher shots, while there is less offset in the short irons for more precision.
The new head shape is extremely forgiving, while enhancing control and accuracy.
