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-Z DRIVER
STRAIGHT-LOW SPIN
With a balanced toe/heel carbon construction and central back weight, Mizuno's ST-Z driver encourages a low spinning, efficient straight ball flight. The modern ground hugging 460cc profile is both confidence inspiring and appealing to elite players. While a heavier 20-gram back weight creates a deeper center of gravity for more efficient performance, more often.
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.

STRAIGHT FLIGHT BIAS
Mizuno’s Z-Axis design - weight is evenly distributed across toe and heel, encouraging a low spinning stable straight flight.

FORGED SAT2041 BETA TI FACE
Maintains its characteristics and resists micro-fractures longer than the commonly used 6-4 Ti. Elevated through a multi-thickness CORTECH design for increased ball speeds.
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
MODERN PLAYERS PROFILE
Full 460cc volume pushed slightly to the ground for higher launch and low/mid spin performance. Visually square to slightly open in the standard-setting.
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.
