About the Mizuno Pro S-1
The Mizuno Pro S-1 features a compact muscleback or minimal cavity design with a thin topline and minimal offset, providing direct feedback and precision shot-shaping at the cost of forgiveness on off-centre hits. At impact it delivers crisp, precise feedback — you will feel every strike clearly, whether it's centred or not.
Loft Analysis
The Mizuno Pro S-1's 7-iron is lofted at 34° — traditional — aligned with classic iron loft standards. For a golfer with an 85–95 mph swing speed, this projects to a 7-iron carry of approximately 136–146 yards. The 5-iron (27°) to 7-iron gap of 7° is well-gapped, which may create overlapping distance windows with similarly lofted fairway woods or hybrids. The pitching wedge at 46° is traditionally lofted, pairing naturally with a standard 52° gap wedge.

- ✓Players who want clear feedback on every miss to improve their technique
- ✓Tour-level players or those aspiring to a professional standard
- ✓Golfers who carry a 7-iron 130–150 yards and want traditional loft gapping
