Mizuno Pro S-1 Irons

These irons are built for skilled players who prioritize shot-shaping, consistent feedback, and precision. Because of their compact profile and focus on workability, they are best suited for mid-to-low handicap golfers who want control over their ball flight.

The copper underlay is placed between the nickel chrome plating and the carbon steel head. It is specifically engineered to provide a softer, more responsive feel at impact, giving you better feedback on how well you struck the ball.

The Triple Cut Sole features relief on the leading and trailing edges, which helps the club glide through the turf more smoothly. This design prevents the club from digging too deep, ensuring cleaner contact even if you strike slightly behind the ball.

While they offer some assistance through the CNC back milling and optimized weight distribution, these are not game-improvement irons. They are designed for precision, meaning off-center hits will be noticeable, providing the honest feedback better players need to improve.

Grain Flow Forging is Mizuno's signature process that maintains the grain structure of the 1025E mild carbon steel throughout the clubhead. This consistency is what gives the irons their solid, dense feel and long-term durability.

Yes, the standard configuration for the Mizuno Pro S-1 irons includes the KBS Tour steel shaft. This shaft is known for its stability and mid-launch characteristics, which complements the performance profile of these forged heads.
