Mizuno ST Max 230 Driver for women
Low profile and wide sole
At first glance, the ST-MAX 230 looks larger than its official 460cc volume would suggest. Its wider sole and low profile give the driver an exceptionally high MOI (moment of inertia). This means it forgives off-center hits and minimizes clubhead twisting at impact. The result is a straighter, more predictable ball flight with a consistent launch angle across the entire face.
CORTECH Chamber
At the heart of the ST-MAX 230 driver technology is the enhanced CORTECH Chamber - a dense stainless-steel component filled with TPU elastomer that “takes” stress off the face while returning energy to the ball. In the ST-MAX 230, this chamber is extended and positioned closer to the clubface, increasing effective speed across an even larger area of the face. As a result, the driver is highly forgiving across different impact points and delivers high ball speed even on off-center hits.
New Beta Rich Ti LFS face
The Beta Rich Ti LFS material is 9% stronger in tensile strength than the previous-generation SAT2041, allowing for a more complex, multi-layer face construction. This lighter, more durable titanium not only increases ball speed on well-struck shots, but also contributes to more consistent launch, even on mishits. This technology was first introduced in the Mizuno Tour ST-G 440cc driver and is now featured in the ST-MAX 230.
Maximum stability
Thanks to a massive 54g weight at the back of the clubhead and a 40% larger share of graphite composite, the ST-MAX 230 delivers exceptional stability at impact. This effectively minimizes clubhead twisting, even on off-center hits, helping you keep the ball on your chosen trajectory with tighter dispersion.
Extended shaft (45 ¾ inches)
An extended shaft is another key to higher swing speeds. Thanks to the improved stability of the clubhead, Mizuno was able to lengthen the driver without compromising control. In practice, this means a faster swing and the potential for longer drives without sacrificing control or accuracy.
Quick Switch Hosel
The ST-MAX 230 features a quick-adjust system for lie and loft across a 4-degree range. This lets you easily fine-tune your ball flight and launch angle to achieve the optimal balance of distance and accuracy for your swing.
