Mizuno ST-X 230 Golf Driver

It took four years of rapid-fire development and worldwide tour usage to raise Mizuno metalwoods from the shadows of our iconic irons. Now, after multiple iterative developments for stability, sound and spin, weve added exceptional ball speeds to our performance equation. Introducing the CORTECH Chamber.

Mizunos CORTECH Chamber encases a stainless steel weight with elastomeric TPU taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact.

A more rounded, deeper profile with weight located closer to the hosel means slightly higher spinning and draw biased for the majority, but more workable for many elite players (especially in lower lofts). Natural drawers of the ball may find more ball speed from the ST-X. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.

The new ST-X 230 is a complex character. Although in the higher loft option its a higher flying draw-biased option, the 9.5 for many of our tour players was more workable and faster from the face. You really need to hit both models before making any judgments on which is likely to work best for you.
