Mizuno ST-X 220 Hybrid
Mizuno — Mizuno ST-X 220 Hybrid · By Troy · Nov 24, 2025
A draw-biased, high-launching hybrid that delivers Mizuno's trademark feel with surprising consistency -- and it does not look or act like a typical game-improvement rescue club.
The Big Picture
Mizuno has spent the last several years proving that its metalwoods deserve to be taken seriously. The ST-X 220 hybrid is part of the third generation of that effort, and it shows. Built as the draw-biased, higher-launching complement to the ST-Z line, the ST-X 220 hybrid is designed for golfers with moderate swing speeds who need elevated launch to maximize carry distance and controlled landing angles. It replaces the older CLK hybrid with a deeper center of gravity, more draw bias, and a higher trajectory.
The construction tells the story. At 1.8 mm thick, the MAS1C maraging steel face is the thinnest Mizuno has ever put on a hybrid, and it produces the highest recorded ball speeds from center strikes compared to any previous ST-X or CLK model. An ultra-thin waffle carbon crown saves weight up top, allowing Mizuno's engineers to push the center of gravity low and deep in the head. The re-engineered Wave Sole is tuned specifically for hybrid play, boosting ball speed on strikes low on the face -- exactly where most amateurs make contact when hitting directly off the turf.
Mizuno's X-Axis design concentrates weight deep in the heel to encourage a natural draw flight without resorting to the visual tricks that plague most draw-biased clubs. There is no aggressively closed face or upright lie angle here. Available in 20, 23, and 26 degree lofts at an original retail price of $224, the ST-X 220 competes directly with hybrids costing significantly more while delivering performance that holds its own against the best in the category.
At Address
This is where the ST-X 220 genuinely surprised me. Most golfers hear "draw bias" and picture a club with an ugly offset, a shut face, and a shape that screams game improvement. The ST-X 220 is nothing like that. The matte black crown is clean and uncluttered, the face sits square behind the ball, and the overall shape is round and confidence-inspiring without looking oversized. There is no mention of draw bias printed anywhere on the head -- you would never know this was a draw model unless someone told you.

The footprint is slightly larger than a compact tour-style hybrid, which is intentional. That extra real estate translates into a more forgiving hitting area and a shape that makes you want to take an aggressive swing. The glossy black finish on some configurations gives it a traditional, understated look both in the bag and at address. Mizuno kept the aesthetics simple and powerful, and it works.
Sound & Feel
Mizuno's Harmonic Impact Research program has been a part of the company's design process for years, and the ST-X 220 hybrid is a clear beneficiary. The sound at impact is a crisp, high-pitched ting that is pleasant without being harsh. It has a touch more metallic character than the ST-X driver, which is typical of maraging steel hybrid faces, but it falls well within the range of what most golfers find satisfying.
Feel is where Mizuno has always distinguished itself, and the ST-X 220 does not disappoint. Center strikes produce a responsive, lively sensation -- you can feel the ball compress and jump off the face. The feedback is clear enough to tell you where you made contact without being punishing on mishits. Off-center strikes still feel solid, with none of the harsh vibration that cheaper hybrids produce. Across multiple testing sessions, the consistency of feel was one of the most impressive aspects of this club.
Performance
Ball Speed & Distance
The headline numbers from my testing were strong. With the 4-hybrid at 20 degrees of loft and a swing speed of about 92 mph, I recorded average ball speeds of 127.7 mph and carry distances of 197 yards. Those are excellent figures for a hybrid in this category, and they speak to how effectively the thin MAS1C face and Wave Sole technology convert swing speed into ball speed.

What impressed me even more was the consistency. During one session, I hit five consecutive shots that all registered 122 mph ball speed. The carry distances ranged from 183 to 186 yards on those swings -- a three-yard spread that I genuinely cannot recall achieving with any other hybrid straight out of the box. That kind of repeatability is rare and speaks to how well-optimized the weight distribution and face design are for maintaining performance across the hitting area.
Launch & Spin
The ST-X 220 launches high and easy. My average launch angle came in at 15.4 degrees with a steep landing angle, which is exactly what you want from a hybrid you are hitting into greens. The ball gets up quickly and comes down soft, giving you the stopping power to hold par-3 greens and attack pins on approach shots.
Spin rates averaged around 4,100 rpm in my testing, which places the ST-X 220 in the mid-to-high spin range for hybrids. That is by design. Mizuno's Director of Product, Chris Voshall, has been vocal about the fact that for many amateur golfers, modern low-spinning metalwood designs are actually distance killers. The ST-X 220 provides enough spin to keep the ball in the air and generate a full, extended ball flight -- a real advantage for players with moderate swing speeds who struggle to get hybrids airborne or keep them up long enough to maximize carry.
Dispersion & Shot Shape
The draw bias is real but subtle. Right-handed golfers will see a consistent tendency for the ball to move gently right to left, which is enough to take the right side of the course out of play without producing an aggressive hook. For the vast majority of amateur golfers who fight a slice, this is exactly the correction they need.

Dispersion was tight. Even on strikes out toward the toe, the ball maintained a similar flight shape and stayed on a predictable line. The deep, heel-weighted center of gravity keeps the head stable through impact, and the forgiveness on mishits was noticeably better than the CLK hybrid it replaces. I could miss it slightly off-center and still expect the ball to finish within a playable window of my target.
One trade-off worth noting: the ST-X 220 has a fixed hosel, meaning there is no loft or lie adjustability. Mizuno made this choice deliberately, reasoning that the eight to ten grams required for an adjustable mechanism could be better spent on optimizing the center of gravity position. It is a fair engineering trade-off, but it means you cannot dial out the draw bias if your swing changes, and you are locked into the stock loft. For golfers who like to tinker, this may be a drawback. For everyone else, the performance gains from that weight savings are worth it.
Verdict
The Mizuno ST-X 220 hybrid is a thoughtfully designed club that delivers where it matters most: consistency, launch, and forgiveness. The maraging steel face produces impressive ball speeds, the high launch and draw bias are genuine game-improvement features for moderate swing speed players, and the shot-to-shot consistency is among the best I have experienced in a hybrid at any price point.
Strengths: exceptional consistency in ball speed and carry distance, easy high launch that helps slower swingers maximize carry, effective but visually disguised draw bias, outstanding sound and feel that lives up to Mizuno's reputation, and a clean appearance at address that inspires confidence without looking like a game-improvement crutch.
Weaknesses: the fixed hosel eliminates any adjustability, the draw bias is baked in and cannot be dialed out for golfers who develop a hook, and it is available in right-hand only. Players who want to work the ball in both directions should look at the ST-Z instead.
The ST-X 220 is best suited for mid-to-high handicap golfers with moderate swing speeds who want a hybrid that launches high, lands soft, and gently corrects a fade or slice. If you have dismissed Mizuno metalwoods in the past based on the brand's iron-centric reputation, the ST-X 220 is a compelling reason to reconsider. It punches well above its price point and holds its own against hybrids from the biggest names in the game.
