Mizuno Road Running Lineup: Wave Rider 28, Wave Sky 8, Rebellion Flash 2 and Pro 2
A close look at four shoes in Mizuno's updated road lineup, from a modernized daily trainer to a marathon super shoe with over 40 mm of midfoot foam.
Introduction
Mizuno is in an interesting place right now. The brand has decades of running heritage, but recent years have seen names like New Balance, Saucony and Hoka dominate the recreational runner conversation. That is starting to change. Mizuno introduced its first marathon racing shoe recently, refreshed it this year, and has been rolling out new models and design features that point to a clear direction for the coming seasons.
Across the core lineup, including the Wave Rider, Inspire and Sky, Mizuno is keeping the familiar designs and ride feelings runners know, while making small tweaks to modernize them. That makes this a good moment to take stock of the road lineup. Here is how four key models break down.
Mizuno Wave Rider 28: The Reliable Daily Trainer, Modernized
If you liked the Wave Rider 27, this update should land well. The headline change is a new foam compound called Mizuno Energy Next. On a hands-on press test it felt very soft, comparable to a premium soft trainer foam, perhaps slightly firmer, with the promise of better durability. Mizuno is known for reliability and quality, and that reputation carries through here.

The classic Mizuno wave plate remains in the midsole, and the thick outsole rubber coverage stays for longevity. The most welcome change is the upper: compared to the slightly dated and heavy Wave Rider 27 upper, this one is much more breathable, with a heel treatment that brings it in line with the best daily trainers on the market. It has a normal tongue and lacing system but a slightly more sock-like feel than before. Think of it alongside shoes like the New Balance 1080 v13: a comfortable upper, soft foam underfoot, and a relaxed everyday ride built to rack up hundreds of miles.
Mizuno Wave Sky 8: Maximum Comfort for Easy Days
The Wave Sky 8 is a bigger visual departure from the Sky 7. The stack height has gone up slightly, and the signature foam bubbles have been enlarged into a huge, comfy cloud of cushioning underfoot. It may not win every beauty contest in the grey colorway shown, but the push test told a different story: this thing feels seriously plush.

The Energy Next foam here is softer than the previous version’s foam, giving a super protective and cushioned ride. The Sky 7 used a dual foam construction with softer foam up top and a firmer layer underneath, and while a layered construction is visible at the top of the midsole, that detail was not confirmed for the Sky 8. Either way, there is a massive stack of Energy Next close to the foot.
Durability fans will love the outsole: it has one of the thickest rubber coverings on any trainer, rivaling the beefiest max-cushion shoes out there. This is the shoe for days after a hard workout, double days, or any run where the goal is to take pressure off your legs.
Mizuno Wave Rebellion Flash 2: A Ground-Up Redesign for Tempo Days
This was arguably the most exciting shoe in the lineup. Every brand needs a strong plated training shoe, and this is Mizuno’s answer to the Saucony Endorphin Speed 3, a shoe Mizuno specifically benchmarked against during development. Where the original Flash was closer to a beefed-up Wave Rider, version two is a complete redesign from the ground up.
The midsole stacks a soft super foam layer on top, the wave plate in the middle, now a more traditional plastic plate like the Endorphin Speed 3 or Mach X rather than the old-school Mizuno wave plate, and a slightly firmer foam layer below with a moderate rubber outsole. The geometry is the boldest change: an aggressively rockered ride Mizuno calls Smooth Speed Assist, plus the heel cut-out carried over from the Wave Rebellion Pro 2, which shifts more foam toward the midfoot.

One open question is how that heel cut-out works for heel strikers. Competitors like the Endorphin Speed 3, Mach X and Boston 12 tend to suit heel strikers thanks to stable, thick rearfoot foam and stabilizing plates. The Flash 2 has less foam in the heel, so runners with less polished form should try it carefully. The upper, though, is a clear win: a hybrid training-racing fit with moderate heel padding, soft laces, and an engineered mesh performance fit that is snug but slightly stretchy through the forefoot, closely modeled on one of the best lockdown uppers in the category. The plate is stiffer than the Endorphin Speed 3’s, so expect a more rigid feel balanced by that softer foam.
Mizuno Wave Rebellion Pro 2: A More Approachable Marathon Racer
The Rebellion Pro 2 is a revision of Mizuno’s first super shoe. It is not dramatically different from version one, but the changes should make it more approachable. The heel foam is now one piece rather than decoupled from the midfoot, giving a smoother ride, and there is a little more cushion at the bottom of the shoe.
The party trick remains the geometry: the midfoot stack exceeds 40 mm while the heel stays at 40 mm, which is how it stays within World Athletics rules despite the funky look of a heel that sits lower than the middle of the shoe. The plate geometry has also been softened so it is less harsh on the lower legs. Version one had a tendency, much like a minimal shoe, to force your lower legs to work hard over a marathon; this one should be easier on the legs and better for recovery.

The upper has been stripped down to save weight, with a lightweight material and a slightly stretchy fabric through the heel area that should offer excellent conforming lockdown. Against established super shoes like the Nike Vaporfly, Adidas Adios Pro 3 and Saucony Endorphin Pro 3, this is one worth putting on the shortlist.
Overall Buying Advice
Mizuno is also preparing a new, not-yet-named high-mileage trainer with a massive foam stack, a sock-fitting upper, and a plastic plate for added snap and rigidity. It uses a soft supercritical EVA midsole rather than a high-energy-return super foam, positioning it as a long, slow distance shoe rather than a fast workout option. The spec is a 45 mm heel stack, 37 mm forefoot, and an 8 mm drop, putting it firmly in the oversized daily trainer category alongside shoes like the Saucony SC Trainer. It serves as a hint of where Mizuno’s lineup is headed over the next few years: more modern tech, while keeping the core Wave Rider and Wave Sky formulas intact for longtime fans.
If you are choosing between these four, a simple rule applies: Wave Rider 28 for dependable everyday miles, Wave Sky 8 for recovery and easy days, Rebellion Flash 2 for tempo runs and race-pace training, and Rebellion Pro 2 for marathon day.
Conclusion
Mizuno’s current road lineup shows a brand honoring its legacy while playing catch-up in the modern performance market. The Wave Rider 28 and Wave Sky 8 refine proven formulas with new foam and better uppers, the Rebellion Flash 2 takes a real swing at the plated trainer category, and the Rebellion Pro 2 makes the super shoe formula a little friendlier. For runners who value durability alongside modern cushioning, this lineup deserves a closer look.
