Mizuno Golf Balls: The Complete Lineup and Buyer's Guide (2026)
Compare all seven Mizuno golf balls by swing speed, spin, and price. Where the Pro S and Pro X tour balls fit, and how they stack up to a Titleist Pro V1.
Quick answer
Mizuno makes seven golf balls, and the right one tracks your swing speed and budget. The Pro S and Pro X are the 2025 tour balls that replaced the older RB Tour and RB Tour X. Fast swingers (105+ mph) want the firm Pro X; most golfers fit the soft, spin-focused Pro S or the value RB Max. Slower swings belong on the low-compression RB 566 or RB 566V. The urethane Pro balls run $10 under a Titleist Pro V1.
Mizuno golf ball lineup at a glance
| Model | Cover | Compression | Spin | Best for | MSRP/dozen |
|---|---|---|---|---|---|
| Mizuno Pro X | Urethane | ~95 (firm) | Mid | 105+ mph, distance | $47.99 |
| Mizuno Pro S | Urethane | ~88 (mid) | High | 90–105 mph, greenside control | $47.99 |
| Mizuno RB Tour X | Urethane | ~95 (firm) | Mid | 105+ mph, prior-gen tour | $42.99 |
| Mizuno RB Tour | Urethane | ~91 (mid-firm) | Low | 105+ mph, prior-gen tour | $42.99 |
| Mizuno RB Max | Ionomer | ~80 (mid) | Low | 90–105 mph, distance value | $29.99 |
| Mizuno RB 566V | Ionomer | ~60 (low) | Mid | Under 95 mph, high launch | $29.99 |
| Mizuno RB 566 | Ionomer | ~60 (low) | Low | Under 95 mph, soft value | $21.99 |
Compression and spin tiers come from BallCaddie’s ball catalog; MyGolfSpy’s gauge reads the urethane RB Tour at 91 and the RB Tour X at 95, matching the brackets above. The four urethane balls (Pro X, Pro S, RB Tour, RB Tour X) deliver tour-level greenside spin, while the ionomer RB Max, RB 566, and RB 566V trade that bite for cover durability and a lower price.
What Mizuno golf balls actually are
Mizuno built its name on forged irons, and the golf balls run on a different model than the clubs. The irons are made in Japan under the brand’s own roof; the balls are not. According to MyGolfSpy’s manufacturing reporting, Mizuno does not own a ball plant and contracts the RB Tour and RB Tour X to Feng Tay in Vietnam, a large factory that also produces balls and footwear for other brands. Mizuno designs the core, mantle, cover, and dimple pattern, then has a specialist build them.
That arrangement is normal for a company that leads with clubs, and the output holds up. MyGolfSpy’s Ball Lab gave the RB Tour X a build-quality score of 84 against a contemporary 73 average, with a True Price only 3% over its $42.99 retail. The earlier RB Tour fared worse on consistency, which is part of why the 2025 Pro series matters: it’s Mizuno’s reset on its own tour ball. The dimple science is genuine too, from the C-Dimple pattern on the RB Tour line to the AXIALFLOW dimples Mizuno now uses on the Pro balls and RB Max to flatten flight in wind.
How to pick a Mizuno ball by swing speed
Swing speed is the first filter because it decides which compression actually returns energy at impact. TrackMan’s amateur data puts the average male driver swing speed near 93 mph and the average woman near 83 mph, which lands most golfers in the soft-to-mid Mizuno range rather than the firm tour end.
- Under 95 mph: the low-compression Mizuno RB 566 (~60) and the higher-launching Mizuno RB 566V (~60) compress easily and hold launch.
- 90–105 mph: the soft Mizuno Pro S (~88) is the urethane all-rounder, and the ionomer Mizuno RB Max (~80) is the value pick for the same swings.
- 105+ mph: the firm Mizuno Pro X (~95) and the prior-generation Mizuno RB Tour X (~95) keep ball speed up and flatten trajectory.
Don’t know your number? The swing-speed fitting framework covers how to measure it and why the compression match matters more at the extremes than in the 85–100 mph middle where most amateurs live.
The tour balls: Pro S, Pro X, and the RB Tour line
Mizuno’s tour-ball story went through a handoff in 2025. The Pro S and Pro X launched as the flagship urethane balls and took over the slot the RB Tour and RB Tour X had held since 2020. The naming maps cleanly: the soft Pro S stands in for the RB Tour, the firm Pro X stands in for the RB Tour X. The older pair stays on the USGA conforming list and keeps selling, usually at a discount, so all four are still worth knowing.
Mizuno Pro S — the soft tour ball
The Pro S is the softer of the two flagships, a 3-piece urethane ball around 88 compression built for feel and greenside control. Mizuno gives it a 332-dimple AXIALFLOW pattern and a cover it markets as 12% thinner, which is consistent with the high greenside spin the catalog lists for it. In one independent launch-monitor test, the Pro S produced 8,133 rpm of backspin on a 50-yard pitch, which the reviewer flagged as above average. It fits the 90–105 mph band and the player who scores on the wedges.
Mizuno Pro X — the fast tour ball
The Pro X is the firmer flagship, a urethane ball around 95 compression aimed at 105-plus mph players who want maximum ball speed. The firm core is the point: at high clubhead speed it holds speed where a softer ball would over-compress and bleed energy. The two flagships ran close in a 97 mph launch-monitor test, with the Pro X spinning a touch more off the driver than the Pro S (2,437 rpm vs 2,266 rpm), which makes the soft Pro S the lower-driver-spin option of the pair. At $47.99 a dozen the Pro X sits $10 under a Titleist Pro V1x (~97).
Mizuno RB Tour and RB Tour X — the prior generation
The RB Tour (~91) and RB Tour X (~95) are the 2020-era urethane tour balls the Pro series replaced. MyGolfSpy called the RB Tour Mizuno’s answer to the Titleist Pro V1 (~87) on compression and feel, and measured the RB Tour X at 95 compression with the strong 84 Ball Lab quality score. Both still hold a conforming spot and tend to surface at discount pricing now that the Pro balls carry the marketing. For a better player chasing tour performance for under $40 a dozen on closeout, the RB Tour X is the sharper buy of the pair.
The performance and value balls: RB Max, RB 566, RB 566V
Below the urethane tour balls, Mizuno runs three ionomer-covered balls built for distance, durability, and price. These trade the tour-level greenside bite for a tougher cover and a lower number on the box. The urethane vs ionomer breakdown explains exactly what that cover swap costs you around the green.
Mizuno RB Max — distance with a durable cover
The RB Max is the bridge ball, a 3-piece ionomer design around 80 compression that Mizuno pitches as tour-like speed and launch with a more durable cover. It uses a dual butadiene-rubber core (soft inner, firmer outer) and a 336-dimple AXIALFLOW pattern for a penetrating, high-launching flight. At $29.99 a dozen it’s the value pick for the 90–105 mph player who wants carry and toughness over wedge spin. Think of it as Mizuno’s honest distance ball, not a tour ball with a discount.
Mizuno RB 566 and RB 566V — soft, high launch, value
The RB 566 (~60) and RB 566V (~60) are the soft, low-compression balls for swings under 95 mph. Both carry the distinctive 566 micro-dimple pattern, which packs small dimples inside larger ones to hold hang time past the apex. The RB 566 is the simpler 2-piece ball at $21.99 and the cheapest Mizuno on the board; the RB 566V is a 3-piece version at $29.99 that launches higher with a touch more spin. Both handle cold weather well, which the firmer Mizuno balls do not, so they double as a shoulder-season option for slower swings.
Mizuno vs Titleist Pro V1: what the data shows
Mizuno’s urethane tour balls compete directly with the Pro V1 line on construction, and the gap is narrower than the brand recognition suggests. The Pro S and Pro X share the urethane cover, multi-layer build, and compression range of the Titleist Pro V1 (~87) and Titleist Pro V1x (~97). Independent reviewers rate the Pro series as legitimate tour-ball competitors, with differences in feel rather than fundamental performance.
| Mizuno Pro X | Titleist Pro V1x | |
|---|---|---|
| Compression | ~95 | ~97 |
| Cover | Urethane | Urethane |
| Construction | Multi-layer | 4-piece |
| Made in | Vietnam (contract) | USA (Titleist plant) |
| MSRP/dozen | $47.99 | $57.99 |
Read it honestly. The Pro V1x earns its premium on proven, in-house quality control and decades of tour usage, and a calibrated short game that lives on spin consistency can feel that edge. For most golfers the gap is smaller than the $10-per-dozen price difference, and the RB Tour X’s 84 Ball Lab score says Mizuno’s contract production can hold tour-grade tolerances. If you want the deeper Titleist context, the Pro V1 vs Pro V1x breakdown maps the two flagships onto swing speed.
The value pick, the flagship, and who should skip Mizuno
The RB Max is the value pick and the Pro X is the flagship, with the Pro S as the tour ball most amateurs should actually play. The RB Max delivers 3-piece construction and a durable cover at $29.99, which fits the widest slice of golfers. The Pro X carries the brand at the top, and the softer Pro S suits the 90–105 mph swing where most buyers live. For a fuller cross-brand picture, see where the value tier lands in the best value golf ball rankings.
Mizuno isn’t the right call for everyone. The honest mismatches:
- You play under 95 mph and grabbed a Pro X or RB Tour X. The firm core needs speed. The RB 566 or RB 566V will out-carry it for you.
- You score on greenside spin and bought the RB Max or an RB 566. The ionomer cover gives up the bite that wins up-and-downs. Stay in the urethane Pro line.
- You want the most proven quality control money can buy. The Pro V1’s in-house tolerances still set the bar, and the early RB Tour showed Mizuno’s contract production can wobble.
- You play a lot of cold golf and want a firm ball. Only the RB 566 and RB 566V are tuned for sub-60°F rounds; the urethane Mizunos feel harsh in the cold.
One thing that is not a concern: conformance. Mizuno’s on-course balls sit on the USGA conforming list and are legal for tournament play. Check the list for the exact model before a competition.

Key takeaways
- Seven balls, two tiers: four urethane tour balls (Pro X, Pro S, RB Tour, RB Tour X) and three ionomer value balls (RB Max, RB 566V, RB 566).
- Pro S and Pro X are the 2025 flagships that replaced the RB Tour and RB Tour X; the older pair still sells, usually discounted.
- Pick by swing speed: Pro X or RB Tour X above 105 mph, Pro S or RB Max at 90–105, RB 566 and RB 566V under 95.
- The Pro balls chase the Pro V1 on construction and compression at $10 less per dozen, with Titleist holding the quality-control edge.
- The savings are structural: Mizuno designs the balls and contracts production to Feng Tay in Vietnam rather than owning a plant.
- All on-course models are USGA conforming — verify the exact model on the current list before tournaments.
Frequently asked questions
- Are Mizuno golf balls any good?
- Yes. Mizuno is best known for forged irons, but its urethane Pro balls compete with premium tour balls at a lower price. In MyGolfSpy Ball Lab testing, the RB Tour X scored 84 against a 73 average, with a True Price only 3% over retail, which signals tight quality control. The newer Pro S and Pro X carry that tour-grade construction forward. The ionomer RB Max, RB 566, and RB 566V are honest distance and value balls rather than tour performers.
- Which Mizuno golf ball should you use?
- Match the ball to your driver swing speed. Above 105 mph, the firm Pro X or RB Tour X suit players who want a penetrating flight. Around 90 to 105 mph, the soft Pro S is the tour-ball all-rounder and the ionomer RB Max is the value alternative. Under 95 mph, the low-compression RB 566 and RB 566V compress more easily and launch higher. If greenside spin is your scoring edge, stay in the urethane Pro line.
- Did the Mizuno Pro S and Pro X replace the RB Tour and RB Tour X?
- Functionally, yes. Mizuno introduced the Pro S and Pro X as its flagship tour balls for the 2025 season, and they now anchor the slot the RB Tour and RB Tour X used to hold. The softer Pro S maps to the RB Tour, and the firmer Pro X maps to the RB Tour X. The older pair stays on the USGA conforming list and still sells, often discounted, so they remain a value-tour option for better players.
- What is the difference between the Mizuno Pro S and Pro X?
- Both are urethane tour balls that fit different swings. The Pro S is the softer ball at around 88 compression, built for greenside control and a soft feel at roughly 90 to 105 mph driver speed. The Pro X is firmer at around 95 compression, aimed at 105-plus mph players who want a penetrating flight and maximum ball speed. In one launch-monitor test at 97 mph, the Pro X produced slightly more driver spin than the Pro S, matching Mizuno's design intent.
- Where are Mizuno golf balls made?
- Mizuno golf balls are made outside Japan, even though the brand's irons are famously forged there. Mizuno does not own a golf-ball factory. According to MyGolfSpy's manufacturing reporting, the RB Tour and RB Tour X are produced in Vietnam by Feng Tay, a large contract manufacturer that builds balls and footwear for several brands. The ionomer RB models are also contract-made in Asia. Mizuno designs the core, mantle, and cover, then has a specialist factory build them.
- Are Mizuno golf balls as good as a Titleist Pro V1?
- Close enough that the choice comes down to feel and price. The Pro S and Pro X share the urethane cover, multi-layer construction, and compression range of the Pro V1 and Pro V1x, and independent reviewers rate them as legitimate tour-ball competitors. The Pro V1 holds an edge in proven, in-house quality control and tour usage. For most golfers, the gap is smaller than the $10-per-dozen price difference, and feel preference should break the tie.
- Are Mizuno golf balls cheaper than Titleist?
- Yes. The flagship Mizuno Pro X and Pro S carry an MSRP of $47.99 per dozen, $10 under the $57.99 of a Titleist Pro V1 or Pro V1x. The prior-generation RB Tour and RB Tour X list at $42.99 and often sell for less at discount, widening the gap. On the value side, the ionomer RB Max is $29.99 and the RB 566 is $21.99, well below anything in the Titleist urethane line.
