Straight. Stable. Low Spinning. A straight bias driver with great stability on off centre hits. Similar in look and character to the previous ST-Z. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.
“Tour tests for the ST 230 SERIES have all been very consistent – relief that the look is similar at address. Then shock at how much better the new ST-Z 230 feels off the face. Ball speeds are up on average 2-5mph with a drop in back spin of around 200 rpm.”
- CHRIS VOSHALL / MIZUNO GOLF
Through slot provides additional corarea by providing sole flex while TPU material allows for sole flexure for face stress reduction. The same TPU material provides sound tuning/damping for enhanced, solid feel.
More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber.
Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.
Mass spread evenly to encourage a highly stable, straight flight ball
Pushed lower to the ground for low / mid spin performance and aligns square to open.
Inserted stainless steel weight is ideally located for spin reduction
The ST-Z 230 Driver is a combination of deeper CG and shorter CG distance for a balance of workability in both directions while providing higher MOI and mid/low spin.
