The irons feature an innovative Channel Back Design, which allows mass to be subtly yet strategically repositioned behind the face. The result is greater vertical MOI and stability, as well as exceptionally consistent launch conditions. Additionally, the channel creates a tour-preferred, firmer, and more responsive impact sensation without sacrificing Mizuno's iconic feel.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMizuno's tour staff also played a pivotal role in developing the Pro S-1's sole. Showcasing a flatter camber profile, a sharpened leading edge, and an increased bounce angle, this new design ensures smoother turf interaction, especially for those with shallower swing paths, while minimizing digging for players who maintain aggressive attack angles.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eMizuno Pro S-1 Irons Feature:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eSingle-piece forged muscle back blade designed for those who prioritize supreme accuracy, precision, workability, and feel\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eGrain Flow Forged HD in Hiroshima, Japan, from a single billet of 1025E Pure Select Mild Carbon Steel with a thin copper underlay to produce Mizuno's legendary feel and feedback\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMore squared-off shape and toe based on Mizuno's tour staff player feedback and input\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eChannel Back Design repositions mass vertically to create greater stability and consistent launch conditions with enhanced responsiveness\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTour-tested sole, including a flatter camber profile, sharpened leading edge, and increased bounce angle, ensures smooth turf interaction and minimizes digging\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNearly identical specs to the Pro S-3 for ease of set blending\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eStock Shaft: KBS TOUR\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eStock Grip: Golf Pride Tour Velvet\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0707\/8723\/6089\/files\/Screen_Shot_2025-10-07_at_12.15.32_PM.png?v=1759853767\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Mizuno","offers":[{"title":"Right Hand \/ KBS Tour 120 Steel Stiff \/ 4-PW","offer_id":46917836800249,"sku":"210000306111","price":1399.99,"currency_code":"USD","in_stock":true},{"title":"Left Hand \/ KBS Tour 120 Steel Stiff \/ 4-PW","offer_id":46917961482489,"sku":"210000306126","price":1399.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/8723\/6089\/files\/mizuno_pro_s_1_irons1.webp?v=1759853977","url":"https:\/\/www.thegolfguys.com\/products\/mizuno-mp-s1-iron-set","provider":"The Golf Guys Online","version":"1.0","type":"link"}
