The Mizuno Wave Horizon 9 is a premium stability daily trainer with aggressive support features for runners who want an incredibly secure shoe for easy weekly mileage. Its firm platform is remarkably stable, making it exceptionally trustworthy underfoot, while the midsole does a decent job of taking the sting out of the road. However, it’s extremely heavy, and its terrible energy return leaves the ride flat and cumbersome when you want to run faster. It’s best suited to relaxed runs of any distance where security matters far more than excitement.

Our Verdict
The Mizuno Wave Horizon 9 is a sub-par pick for marathon racing. Though it's outstandingly stable and trustworthy when fatigued, and the cushioning holds up adequately over longer efforts, its extreme weight is very cumbersome underfoot. The midsole returns very little energy at either end of the shoe, too, so there's simply not enough efficiency here to help find a rhythm and sustain a pace.
Outstanding stability remains trustworthy when fatigued.
Extreme weight makes turning the shoe over exhausting.
Awful energy return makes finding and sustaining pace very hard.
Poor forefoot bending energy return makes toe-off very inefficient.
The Mizuno Wave Horizon 9 is a sub-par pick for short-distance racing. Its very firm forefoot provides a secure platform to push from, while the forefoot rocker geometry offers good assistance through toe-off. It also takes a decent amount of force to bend, giving you some leverage, but the forefoot itself isn't stiff enough to produce much snap. Combined with its extreme weight, compliant rocker, and poor energy return, the shoe is far too cumbersome for fast running.
Very firm forefoot and good rocker geometry provide a secure, guided toe-off.
Extreme weight makes fast turnover difficult.
Poor energy return and compliant rocker limit efficiency.
Forefoot isn’t stiff enough to generate much snap.
The Mizuno Wave Horizon 9 is a decent long-run shoe for relaxed efforts. Its outstanding stability keeps the ride exceptionally secure as fatigue builds, while the cushioning remains adequately protective deep into longer runs. The forefoot rocker also delivers a very guided toe-off. However, the rocker is too compliant to provide much assistance, and the shoe's extreme weight becomes increasingly cumbersome as the miles build, making it unsuited to anything beyond easy paces.

The Mizuno Wave Horizon 9 is a good daily trainer for runners who prioritize security. Its outstanding stability makes every stride exceptionally trustworthy, while the decent cushioning takes enough sting out of regular mileage. However, the shoe is extremely heavy and returns very little energy, leaving the ride flat when you want to run faster. It's at its best for easy runs where dependability matters more than excitement.
Remarkably trustworthy through stride.
Decent impact protection for routine miles.
Unplated design makes ride accessible for all runners.
Not suited to anything beyond relaxed mileage.

Test Results
Energy Return
The Mizuno Wave Horizon 9 does a very bad job of returning energy. Both the heel and forefoot do an awful job of rewarding the effort you put into the midsole, leaving the ride very flat underfoot. That said, this fits the shoe's profile of a secure and reliable shoe as opposed to an exciting one.
Very little rebound from either the heel or forefoot.
Flat ride offers almost minimal help when you want to run faster.
Poor efficiency makes the shoe more tiring to turn over.
Stability
The Mizuno Wave Horizon 9 has absolutely outstanding stability. Its very firm heel and forefoot keep the shoe exceptionally secure under load, while the broad heel and wide arch provide a remarkably trustworthy base through the whole stride. There's also plenty of width at the forefoot, so the shoe remains reliable no matter where you land. It also has very aggressive support features baked into its geometry to help achieve the remarkably reliable ride.
Wide arch provides a remarkably secure base through midstance.
Very firm heel keeps landings exceptionally controlled.
Very firm forefoot provides a dependable platform at toe-off.
Broad platform keeps the shoe trustworthy across all foot strikes.
The Mizuno Wave Horizon 9 has a very firm heel across all force levels. It keeps landings very controlled under load, contributing to the shoe’s outstanding stability
The forefoot is also very firm across different force levels. It provides a highly secure platform at toe-off, helping the shoe remain exceptionally stable through the latter part of the stride
The Mizuno Wave Horizon 9 uses a fully gusseted tongue, which helps keep the foot securely locked down, and it has no plate (unlike the Mizuno Wave Inspire 22).
Cushioning
The Mizuno Wave Horizon 9 is decently cushioned overall. The forefoot offers the best protection for lighter runners at easy paces, but becomes harsher the more you load the shoe. The heel is more consistent, however, with the best protection at moderate forces and satisfactory shock absorption at light and high force levels. The midsole also doesn't bottom out on longer efforts.
Forefoot offers great protection for lighter runners at easy paces.
Heel offers consistent protection across all force levels.
Forefoot becomes much harsher as more force is applied.
The heel is decently cushioned overall, offering the best protection under moderate force levels.
The forefoot cushioning is great for lighter runners at easy paces, but protection drops off as force increases, so heavier runners at faster paces will find the ride harsher underfoot.
The forefoot cushioning holds up adequately over longer efforts and doesn't bottom out as the miles build. It's more protective than the Brooks Glycerin GTS 23 or Mizuno Wave Inspire 22, though it can't match more modern options like the Saucony Hurricane 26.
Bounciness
The Mizuno Wave Horizon 9 isn't a bouncy shoe. Neither the heel nor forefoot compresses deeply enough to create much spring, and the very poor energy return means the ride is flat with very little give-and-return underfoot.
Midsole doesn’t compress deeply enough to generate much spring.
Very poor energy return further limits bounce.
Ride feels flat rather than lively.
Snappiness
The Mizuno Wave Horizon 9 has an acceptable amount of snap. Though the forefoot takes a decent amount of force to bend, providing some leverage at toe-off, it isn't stiff enough to generate much snap. It also returns little of the energy stored as it bends, limiting efficiency as it unbends. That said, the forefoot rocker does a good job of rolling the foot forward through toe-off, so it provides some assistance at push-off.
Forefoot takes enough force to bend to provide some leverage at toe-off.
Forefoot rocker helps roll the foot forward through push-off.
Forefoot isn’t stiff enough to generate much snap.
Poor bending energy return limits efficiency at toe-off.
This shoe has poor forefoot bending energy return. It loses a lot of the energy stored as the shoe bends, limiting efficiency as it unbends through toe-off.
The forefoot takes a lot of force to bend, providing some leverage at toe-off. However, the forefoot itself is too compliant to generate much snap, so that leverage doesn't translate into an especially snappy push-off.
The forefoot rocker does a good job of rolling the foot forward through late stance and into toe-off. It's much more assistive in transition than the Mizuno Wave Inspire 22, so push-off is much more fluid despite its bulk.
Roll
The Mizuno Wave Horizon 9 rolls adequately through stride. The forefoot rocker does a good job of rolling the foot forward through late stance and into toe-off, but the heel rocker provides little assistance transitioning into midstance. The rocker also flattens too easily under load, limiting how smoothly and efficiently the shoe carries you from landing through push-off.
Forefoot rocker rolls the foot forward smoothly through toe-off.
Heel rocker provides little assistance transitioning into midstance.
The Mizuno Wave Horizon 9 has a compliant rocker that flattens relatively easily under load. This limits the mechanical assistance the shoe provides, reducing how smoothly it carries you through the stride.
The Mizuno Wave Horizon 9 has a tall stack under both the heel and forefoot. Its traditional drop makes it suited to all strike patterns.
Though more assistive than in shoes like the Brooks Glycerin GTS 23, the heel rocker of this shoe still provides limited assistance after landing. Heel strikers won’t get much help rolling forward into midstance, so the early part of the stride can feel clunky.
True To Size
The Mizuno Wave Horizon 9 fits remarkably true to size. The length is spot-on, while the forefoot and arch widths closely match our reference fit. There’s also enough vertical room in the forefoot for most runners, so runners can choose their usual size.
Length is spot-on.
Forefoot width closely matches our reference fit.
Arch width should suit most runners.
Forefoot provides enough vertical room for most feet.
The Mizuno Wave Horizon 9 is a very heavy shoe, and its bulk is immediately noticeable underfoot. It's cumbersome to turn over, making it much better suited to relaxed mileage than faster running.
The Mizuno Wave Horizon 9 uses a dual-foam midsole, with a softer layer directly underfoot and a firmer layer underneath to create a more stable base. The setup delivers decent cushioning, but it’s clearly tuned more for protection and security than energy return.
This shoe uses standard flat laces with low stretch. They kept lockdown consistent during our testing without any lace bite or need to re-tie.
The Mizuno Wave Horizon 9's thick knit upper runs quite warm, so your feet may overheat on hot days or if you wear thicker socks.
Popular Running Shoe Comparisons
The Mizuno Wave Horizon 9 is the brand's premium support trainer, costing significantly more than the cheaper, plated support shoe, the Mizuno Wave Inspire 22. It's more cushioned, more stable, and better suited to longer efforts, though it's significantly more cumbersome underfoot, and its very assertive support may be overkill unless you have substantial stability needs. Elsewhere in the market, the Brooks Glycerin GTS 23 costs about the same and offers great stability with a less aggressive support setup, though it's a touch less cushioned overall. If your support needs are milder and you want a much more enjoyable daily trainer, check out the Saucony Hurricane 26.

The Mizuno Wave Horizon 9 and Brooks Glycerin GTS 23 are both premium stability trainers that cost the same, but they suit slightly different runners. The Horizon 9 is more stable and a touch better cushioned, while the Glycerin GTS 23 is a hair lighter and provides support in a less intrusive way. Neither is particularly lively, so the decision mostly comes down to support needs: get the Horizon 9 if you need the most secure ride possible; get the Glycerin GTS 23 if you want a more of a stability shoe with gentler support.
The Mizuno Wave Horizon 9 is a better shoe than the Mizuno Wave Inspire 22. Though both are stability shoes, the Horizon 9 is more stable, absorbs more impact, and is better suited to longer efforts. However, it's more expensive and significantly heavier than the Inspire 22, and its support features are much more assertive. Get the Inspire 22 if you want a cheaper stability shoe with a plated ride and don't need as much support; get the Horizon 9 if you want maximum security underfoot with the most protection of the two and don't mind paying a premium.
Differences Between Sizes And Variants
We tested the Mizuno Wave Horizon 9 in men's U.S. size 9, as noted on the label for our pair. The color shown here is FOGGY DEW-DARK SLATE. This model is also available in other colorways depending on your region. A wide version is available for both men (2E) and women (1D). The design section applies only to the exact model we tested, but we expect other size and gender variants to perform similarly.
