The Next Generation of Stability

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.

More Performance.
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.


Engineered for 'more often'

Engineered for 'more often'

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.

How Mizuno's engineers added exceptional stability to the ST-Z and ST-X 220 Series.

Focus on Launch Stability

Focus on Launch Stability
01

Ball Speed

CORTECH, SAT2041 Beta Titanium, WAVE, and CT ribs contribute to higher speed and larger CORAREA

02

Launch Angle

At impact depends on dynamic loft, attack angle, and impact position relative to the Sweet Spot

03

Back Spin

At impact depends on attack angle, dynamic loft, and impact position relative to Sweet Spot

Mizuno ST-220 Series

"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."

Mizuno ST-220 Series

"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.

DAVID LLEWELLYN / DIRECTOR OF R&D

Mizuno ST-220 Series

"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."

Mizuno ST-220 Series

"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."
