The ST-X 220 is Mizuno's answer to a slice. It sits next to the ST-Z 220 in the 2022 lineup, and the split is simple: the Z is the neutral head, the X leans the weighting toward the heel to help you turn the ball over. If your misses drift right and you want the ball to launch higher without a fight, this is the one Mizuno built for you.

Mizuno spent years known for irons, and the driver reputation lagged behind. The ST series changed that. The 220 carries a forged SAT2041 Beta Titanium face, which is stiffer and lets Mizuno stretch the thin, hot part of the face wider. Behind it sits the CORTECH Chamber, a weighted piece in the sole that lowers the center of gravity and keeps ball speed up on strikes off the middle. The crown is carbon composite, which frees up weight to push where it matters.

Where that weight goes is the whole point of the X. It sits toward the heel, so the face wants to square up through impact. Pair that with the high-launch setup and you get a driver that fights the two-way miss a lot of mid handicappers live with: the low, weak slice. It won't cure a bad swing, but it tilts the odds back toward the middle of the fairway.

• You fight a slice or a weak fade and want the driver itself helping square the face.
• Your swing speed is moderate and you need help getting the ball up and carrying it.
• You want Mizuno's forged-face feel and sound without stepping up to a low-spin tour head.
• You'd rather adjust loft and lie in the hosel than manage a sliding weight track.

よくある質問

What's the difference between the Mizuno ST-X 220 and the ST-Z 220?

The ST-X 220 has heel-biased weighting and a higher-launch setup to help square the face and fight a slice. The ST-Z 220 is the neutral, lower-spin head aimed at players who already deliver the club squarely and want to shape shots both ways. Same face and chamber tech, different weighting.

Is the ST-X 220 good for a slicer?

Yes, that's the head's job. The weight sits toward the heel to help the face close through impact, and the higher launch keeps slice-prone shots from ballooning weakly to the right. It reduces a slice; it doesn't erase a badly out-to-in swing path.

Is the ST-X 220 adjustable?

It has an adjustable hosel that changes loft and lie, so you can fine-tune launch and how much the ball draws. There's no sliding sole weight, so setup is limited to the sleeve. That keeps it simple, but it's less configurable than heads with a movable track.

What swing speed suits the ST-X 220?

It fits moderate swing speeds best, roughly the 85 to 100 mph driver range where launch and carry are the priority. Faster players who spin the ball too much or want a lower, more penetrating flight will usually prefer the ST-Z 220 or a low-spin head.

What face and materials does the ST-X 220 use?

The face is forged SAT2041 Beta Titanium, which is stiff and lets Mizuno widen the fast part of the face. The crown is carbon composite to save weight, and the sole holds the CORTECH Chamber, a weighted insert that lowers the center of gravity and protects ball speed on off-center hits.
