What You Need to Know
The S-series already included the S-1 blade and S-3 players cavity back. The S-4 adds more forgiveness while keeping the same finish, head profile, and lofts, so mixed sets are straightforward.
Mizuno repositioned mass lower in the head and refined the geometry to help the iron launch higher and feel more stable, without giving up the precision expected from a Mizuno Pro iron.

Chris Voshall, Mizuno Director of Golf: “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.”
