{"product_id":"21126","title":"Mizuno Pro S4 Iron Set","description":"\u003cp\u003e\u003cspan\u003eThe Mizuno Pro S-4 irons represent the evolution of Mizuno’s renowned forging craftsmanship, blending the refined precision of a player’s iron with enhanced forgiveness and stability. Designed for golfers who demand exceptional feel without sacrificing playability, the Pro S-4 features a slightly more forgiving profile with graduated offset, a wider sole, and a deeper center of gravity for improved launch, consistency, and control. A lower sweet spot further enhances performance from a variety of turf conditions and strike locations, while preserving the compact shaping, soft feel, and shot-making versatility expected from the Mizuno Pro series.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGrain Flow Forged HD: One-piece Grain Flow Forged HD from 1025E Pure Select mile carbon steel at Mizuno's iconic facility in Hiroshima, Japan.
