ICONIC MIZUNO PRO FEEL The Mizuno Pro S-1 delivers the unmistakable sensation that Mizuno irons are famous for. Built using Mizuno’s exclusive Grain Flow Forged HD process in Hiroshima, Japan, and paired with premium materials, the S-1 irons are designed to provide unparalleled feel and responsiveness. 1025E Pure Select Mild Carbon Steel for soft, consistent feedback. Copper Underlay enhances vibration patterns for smoother impact sensation. CHANNEL BACK DESIGN The innovative Channel Back Design of the Mizuno Pro S-1 Irons subtly repositions mass directly behind the face to deliver a more stable vertical centre of gravity. This precision weighting creates more consistent launch conditions across the set, giving golfers greater confidence in distance control. At the same time, the Channel Back construction provides a firmer, tour-preferred feel through impact, enhancing responsiveness without compromising the signature soft Mizuno forged feel players demand. TOUR-TESTED AND CONFIRMED SOLE The Mizuno Pro S-1 Irons feature a sole design that has been meticulously refined through direct tour player feedback. With a flatter camber profile, a sharper leading edge, and increased bounce angle, the sole promotes smoother turf interaction across varying course conditions. This precision engineering is especially beneficial for players with shallower swings, as it reduces digging while maintaining confidence at impact. The result is an iron that allows golfers to take aggressive angles of attack with control and consistency, delivering both playability and tour-level performance. TRIPLE CUT SOLE TECHNOLOGY Designed to optimise turf interaction, Mizuno’s Triple Cut Sole ensures consistency and playability in all conditions. Bevelled leading edge improves strike consistency through the turf. Trailing edge relief enhances exit through impact. Optimised sole geometry provides confidence across varied lies. PURE PRECISION FOR THE MODERN PLAYER The Mizuno Pro S-1 Irons combine heritage forging expertise with a refined profile designed for shot-shapers. For players who value feedback, trajectory control, and precision distance gapping, the S-1 is the ultimate choice.
