Mizuno ST-X 220 Driver


Heel Biased/Back Weight

Mizuno ST-X 220 Driver

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.

Golf Digest Badge
“For a lot of golfers, the modern low spinning driver design preferred by tour players is a serious distance killer. The ST-X’s extra spin, slight draw bias and a higher flight will add driving distance for a surprising number of players.”


More Performance. More Often.

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.
