Mizuno ST-X 230 Driver

A rounded, deeper profile with a weight positioned closer to the hosel means a bit more spin and draw for most players, but it is more practical for many elite players (especially at lower lofts). Natural ball drawers can find more ball speed with the ST-X. The CORTECH Chamber ensures that the ball comes off the face faster, has less spin, and provides an incredible, solid feel at impact.

CORTECH Chamber - The missing piece: Mizuno's CORTECH Chamber encases a dense stainless steel weight with elastic TPU, which relieves stress from the face and creates an additional source of energy. At the same time, the weight is placed closer to the face to reduce spin rate, contributing to a more solid, powerful feel at impact.

Forged SAT 2041 Beta Ti face: More elastic than the commonly used 6-4 Ti, with a more complex multi-thickness design enabled by Mizuno's CORTECH Chamber.

Unified sole material: The carbon sole plate is now a single piece to push the weight to the extreme and enhance stability.

Workable / Draw bias: The weight is positioned closer to the shaft axis, which can lead to a more playable or more draw-biased outcome depending on the player.

Deeper profile: A rounder appearance that sits a bit higher. Aligns squarely in the neutral setting.

Quick Switch hosel: 4 degrees of adjustability.
