Legacy Reborn
The Mizuno Pro S-4 has been engineered for accomplished golfers seeking the unmistakable feel of a forged iron with greater forgiveness and confidence throughout the set. A redesigned curved muscle concentrates mass lower in the head, while progressive offset, a wider sole and deeper center of gravity promote higher launch, increased stability and improved forgiveness without compromising the precision expected from Mizuno Pro. Forged from a single billet of 1025E Mild Carbon Steel using Mizuno’s patented Grain Flow Forged HD process, the S-4 delivers the exceptional feel, feedback and workability synonymous with Mizuno’s forged heritage.
“The S-4 has been developed for players who appreciate the feel of a traditional forged iron but want greater confidence through increased forgiveness. By repositioning mass lower in the head and refining the head geometry, we’ve created an iron that launches higher, offers more stability and inspires confidence without sacrificing the precision expected from Mizuno Pro.” John Freeman – Senior R&D Engineer
