The Mizuno Pro S-4 is engineered for accomplished golfers who want 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, delivering higher launch and increased stability without compromising the precision expected from a Mizuno Pro set. Progressive head geometry runs through the S-4: increased offset, a wider sole and a deeper centre of gravity inspire confidence at address while promoting easier launch and greater forgiveness. Forged from a single billet of 1025E Mild Carbon Steel in Hiroshima, Japan, the S-4 carries the feel, feedback and workability that define Mizuno's forged heritage.
The reshaped muscle concentrates mass lower in the head to deliver increased forgiveness, higher launch and greater stability – all while maintaining the classic Mizuno Pro profile behind the ball. More help on mishits, without the bulky look that usually comes with it.
Forged from a single billet of 1025E Mild Carbon Steel in Hiroshima, Japan, using Mizuno's patented Grain Flow Forged HD process. A copper underlay beneath the finish further enhances the soft, responsive feel that has become synonymous with Mizuno Pro forged irons.
Beveled leading and trailing edges improve turf interaction for smoother entry and exit through impact. Paired with Harmonic Impact Technology, which tunes vibration characteristics precisely, the S-4 produces the solid, refined impact sensation expected from Mizuno's premium forged irons.
