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 to 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.
ST-X DRIVER
ULTRA-STABLE WITH HIGH DRAW BIAS
A confidence-inspiring, draw-biased driver with heel focused weight location. The ST-X will appeal to players seeking a higher, right to left ball flight. With higher spin rates than its ST-Z counterpart, the ST-X will suit moderate swing speeds, needing help producing a more extended ball flight. A new 20-gram heel biased back weight creates a deeper center of gravity for more efficient, longer drives - more often. Also available as a J-Spec option with ultra-lightweight HELIUM Nanocore shaft for seniors and slower swing speeds.
FEATURES & TECHNOLOGY
NEW OPTIMALLY PLACED 20G STAINLESS STEEL WEIGHT
Positioned below the sole surface and extreme center, rear of the head, provides a huge MOI boost without sacrificing spin performance.
HIGH DRAW FLIGHT BIAS
Mizuno’s X-Axis design - weight is focused deep in the heel, encouraging a higher draw bias flight.
FORGED SAT2041 BETA TI FACE
17% stronger than the commercial 6-4 Ti. Provides enhanced COR to CT performance.
FOCUS ON LAUNCH STABILITY
BALL SPEED
CORTECH, SAT2041 Beta Titanium, WAVE, and CT ribs contribute to higher speed and larger CORAREA
LAUNCH ANGLE
At impact depends on dynamic loft, attack angle, and impact position relative to the Sweet Spot
BACK SPIN
At impact depends on attack angle, dynamic loft, and impact position relative to Sweet Spot
SLIGHTLY ROUNDED PROFILE
A rounded 460cc volume for higher launch and mid spin performance.
ENGINEERED FOR 'SOLID' FEEL
Mizuno's Harmonic Impact Research identifies and isolates vibration patterns that elite players associate with a preferred 'solid' feel. Knowledge of exact, preferred vibrations allows Mizuno to build sound into the design.
OPTIMIZED WAVE SOLE
Delivers an additional contribution to ball speeds, particularly from low on the club face.
QUICK SWITCH ADJUSTABILITY
With 4 degrees of loft adjustability to fine-tune launch and trajectory.
