A confidence-inspiring, draw-biased driver with heel focussed 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 centre 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.
The ST-X delivers your optimum 'more often' through exceptional stability from off-centre strikes. An expansion of the carbon sole area by 40% and thinning out the Titanium portion. Alongside a near doubling of the stabilizing heel/back weight.
Maintains its characteristics and resists micro-fractures longer than the commonly used 6-4 Ti. Elevated though a mutli-thickness CORTECH design for increased ball speeds.
 Mizuno’s X-Axis design - weight is focussed deep in the heel, encouraging a higher draw bias flight.
With 4 degrees of loft adjustability to fine-tune launch and trajectory.
