Mizuno Pro S-4 Irons

The 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.
