Nike Pro Combo irons are a set of irons that offer the ideal club for every shot. The focus within a set should start with forgiveness in the long irons and transition into feel into short irons. Different types of shots require distinct clubhead mass distribution. Lower centre of gravity in the long irons enhance trajectory and resist twisting at impact. Mid irons balance forgiveness and feel. Short irons complete the transition to feel. The Nike Pro Combo irons have a progressively higher centre of gravity prevents shots from ballooning. Centre of gravity moves gradually higher and towards the toe making it easier to hit long irons square while reducing pulled shots in short irons. Two-step forging process eliminates soft and hot spots for a more consistent ball striking surface. Proprietary U/V scoring grooves enhance spin, trajectory and distance control. Constant weight steel shaft ensures consistent feel from club to club. Clubheads are finished with a deep, durable Tri-Plex nickel and chrome plating and buffed to a high-satin-gloss finish.
