If you’ve been waiting for an On shoe that can truly do it all, the On Cloudboom Max might be it. This shoe blends max cushioning with a glass fiber–infused Speedboard, giving you a lively yet protected ride that feels just as good on recovery walks as it does on fast-paced workouts. It’s rare to find a super shoe that doubles as a comfortable daily trainer, but the Cloudboom Max manages to hit that sweet spot with smooth transitions and all-day comfort.
What sets it apart from On’s past racers is its stability and versatility. The stable Helion HF hyper foam feels more grounded, making it one of the brand’s more stable options, while the airy, breathable upper keeps your feet cool even in hot conditions. Whether you’re logging easy miles, gearing up for long runs, or chasing a marathon PR, the Cloudboom Max was built with speed-focused long-distance runners in mind—without leaving comfort behind.

Design & Build
The On Cloudboom Max looks and feels every bit like a race-day weapon, but with a touch of comfort you don’t always find in super shoes. The ultralight mesh upper is insanely breathable, making it perfect for hot weather runs where lesser shoes might turn into saunas. A thin, gusseted tongue keeps everything in place without adding bulk, and the lightweight padding is placed exactly where you need it—nothing more, nothing less. Step in, and you’ll notice that classic snug, racing-shoe fit, but with a toe box that actually gives your toes some breathing room.
Lockdown is where this shoe quietly impresses. The gusseted tongue works with the laces to wrap the midfoot securely, while the lightly padded heel counter keeps your foot anchored without overdoing the cushioning. No heel slip, no pressure points—just a locked-in, ready-to-go feel. Visually, the upper nails that sleek, aerodynamic vibe On is known for, with details that scream “marathon day.” And the best part? Breathability is top-notch, with no hot spots to complain about, even when the sun is blazing.
Midsole & Cushioning
The On Cloudboom Max delivers a ride that feels versatile enough to handle just about anything you throw at it—whether it’s a slow recovery run, a long grind, a faster workout, or even an all-day walk. Sitting on a generous 40/32 mm stack (8 mm drop) of Helion HF superfoam, it soaks up impact beautifully without ever feeling mushy or overly firm. Landings are soft yet controlled, and toe-offs come with a nice pop of energy that keeps you moving forward without demanding extra effort. The glass fiber–infused Speedboard adds a supportive backbone, guiding each stride into a smooth transition and finishing with a snappy push-off.
What makes this shoe stand out in On’s lineup is how balanced and stable it feels. The gentle rocker geometry works with you rather than against you, smoothing out transitions at both slower and faster paces. It’s not an aggressive, all-out racing rocker like some marathon super shoes—it’s more of a steady, versatile platform that feels comfortable mile after mile. And beyond the run, the Cloudboom Max is easy to slip on and just as enjoyable for walking or standing for long periods, making it one of the most practical “super shoes” you can actually live in day to day.
Outsole & Traction
Flip the On Cloudboom Max over, and you’ll see a thoughtful outsole design that balances durability, grip, and weight savings. On placed thick rubber in the high-wear zones, which means the parts that hit the ground hardest are well-protected, while the midfoot is left with exposed foam to shave ounces and deliver softer landings. It’s a smart setup—keeping the shoe light without sacrificing longevity where it matters most.
As you’d expect from On, the rubber itself feels premium and built to last. Honestly, this outsole could outlive the upper, which says a lot about its durability. Traction is solid, gripping confidently on pavement, track, and even wet roads, so you won’t feel sketchy cornering at speed. The outsole design also works in harmony with the shoe’s rocker and Speedboard, giving the Cloudboom Max that quick, efficient turnover that makes it feel race-ready without being overly aggressive.
Performance on the Run
On the road, the Cloudboom Max feels smooth, stable, and surprisingly adaptable no matter the pace. The ride has a nice balance—responsive enough to keep you moving during quicker efforts yet cushioned enough to make long miles feel less punishing. Transitions are seamless, helped along by the gentle rocker and Speedboard, so each stride feels fluid rather than forced.
Where this shoe shines is in its versatility: it can handle marathon racing, tempo sessions, and long-distance training without skipping a beat. The energy return is lively, giving you that extra spring without tipping into the overly aggressive, carbon-plated racer territory. Efficiency is on par with top-tier trainers, making it a serious contender for anyone who wants one shoe that can cover both daily mileage and race day without compromise.
Comfort & Fit
Slip into the On Cloudboom Max and the first thing you’ll notice is how comfortable it feels for a shoe built with race-day intentions. The step-in experience is soft and secure, giving you that snug, locked-in fit you expect from a performance trainer without crossing into restrictive territory. It fits true to size, with a nicely balanced heel and midfoot lockdown that keeps you planted, plus a roomy toe box that lets your toes splay naturally on longer runs.
That combination of secure fit and extra breathing room pays off big in terms of endurance. Even over marathon distances, the shoe holds its shape and delivers consistent performance, so you don’t feel like it’s giving up on you at mile 20. In short, it’s a rare super shoe that manages to feel fast, comfortable, and supportive all at once.
Durability & Value
You can expect somewhere between 300 and 500 miles out of the On Cloudboom Max, depending on your running style and how often you rotate shoes—but even at the upper end, it holds up impressively well. The outsole rubber feels built to last, and the upper remains serviceable longer than you might think for a high-performance shoe.
In terms of price, the Cloudboom Max is a steal compared to some of its carbon-plate rivals, especially if you’re looking at shoes like the Nike Alphafly 3 or Saucony Endorphin Elite 2. You get a lot of similar “super shoe” tech (high stack height, a Speedboard, breathable upper) without the typically sky-high price tag.
If you’re a runner who wants a single shoe that can handle everyday mileage, long runs, and occasional fast efforts without needing a closet full of specialists, the Cloudboom Max delivers serious bang for your buck.
Pros & Cons
Pros
- Versatile super-shoe that works well across paces — recovery jogs, long runs, tempos, and racing
- Excellent balance of cushioning and responsiveness from Helion HF foam and glass-fiber Speedboard
- Breathable, lightweight upper with snug midfoot lockdown and roomy toe box
- Stable ride for a fiber-infused trainer / racer hybrid
- Durable outsole rubber and decent overall mileage for its class
- More affordable than many carbon-plated competitors
Cons
- Still not as fast or aggressive as a dedicated carbon-plated racer

- Stability is better than some On racers, but still not as planted as full-blown stability trainers
- Price may deter budget runners who don’t need “super shoe” features
Who Should (and Shouldn’t) Buy the On Cloudboom Max
Should buy if you …
- Want a do-it-all running shoe that can handle long runs, tempo efforts, and even race day without switching models.
- Like the idea of a glass fiber-infused “super shoe” but prefer something more forgiving and stable than a razor-sharp racer.
- Live or train in hot, humid conditions and need a highly breathable, lightweight upper that can also hold up over long miles.
- Are looking for a single trainer that can pull double (or triple) duty—daily miles, long runs, and speed sessions—with comfort and durability.
Might want to look elsewhere if you …
- Prioritize maximum speed and aggressive propulsion over versatility and comfort (you’d probably be better off with a pure racing flat or full-blown carbon plate racer).
- Have a tight budget and only need a basic trainer or recovery shoe—super-shoe tech may be overkill.
- Require very specific stability features (e.g. motion-control midsoles) or have extreme biomechanical needs—it’s more stable than many On racers, but it’s not a specialized stability shoe.
- Prefer ultra-lightweight minimalism over cushioning and aren’t comfortable with a higher stack and rocker geometry.
Final Verdict: On Cloudboom Max
The On Cloudboom Max stands out as one of the rare “super shoes” that you can actually live in—an everyday runner that’s ready for race day. Its double layer of Helion HF cushioning, glass fiber-infused Speedboard, and stable yet airy upper gives you a ride that’s simultaneously comfy, responsive, and versatile.
If you’re after a single pair that can comfortably shoulder long runs, tempos, recovery jogs, and fast efforts with consistency and durability, the Cloudboom Max is a smart investment, especially compared to pricier carbon-plated racers. Unless your priority is outright max speed or ultra-minimal weight, this shoe delivers serious bang for your buck without feeling like a compromise trainer lurking in racing gear.
