Once ball speed is maximized with launch angle and spin rates optimized – the final route to elevated driving performance on the course is greater consistency. Step up the Next Generation of Mizuno's ST Series – the new ST-Z 220 and ST-X 220. Engineered to produce your most efficient drives and highest ball speeds ...more often.
The Next Generation ST-Z and ST-X deliver your optimum 'more often,' through exceptional stability and consistency from off-centre strikes.
An expansion of the carbon-sole area by 40% and thinning out the Titanium portion, alongside a doubling of the stabilizing back weight.
With pressure on, out on the course, that's more consistent ball speed, more consistent launch angle and spin. Your most efficient drives – more often.
CORTECH, SAT2041 Beta Titanium, WAVE, and CT ribs contribute to higher speed and larger CORAREA

"Once ball speed is maximized - with launch angle, and spin rate optimized the last way to increase driver performance is via stability. Any twisting or deflecting at impact due to an off-centre hit is an energy loss and varies launch conditions."
"By working with the prior ST driver platform and familiar materials, we were able to find several adaptations to impact the internal weighting. Creating far more stable tendencies in both the ST-Z and ST-X.

"By early 2021, with the vast majority of tour players we tested, the ST SERIES drivers were able to improve on their current driver for ball speed, looks and feel. The occasional barrier to getting a driver in play was the distance drop off from off-centre strikes."
"Our engineers isolated and tackled that last dimension with the new ST-Z and ST-X. We're now seeing the results – ball speed drop-offs are negligible, and we’ve massively tightened the overall ranges of launch and spin."
