On Cloudmonster Review: The Max-Cushion Running Shoe That Feels Like a Trampoline for Your Feet

On Cloudmonster takes On’s signature CloudTec cushioning and dials it up to ridiculous levels. If your legs are tired of harsh pavement but you still want a light, energetic shoe for daily miles, this might be the most fun road runner you can buy right now.

Most road runs start to feel the same. The first mile is hopeful, the middle is noisy knees and tight calves, and by the end youre counting cracks in the pavement just to distract yourself from the pounding underfoot. You dont notice your shoe as much as you notice the fatigue it isnt preventing.

If that sounds familiar, youre exactly the runner the On Cloudmonster is built for.

Ons maximalist daily trainer takes the brands famous CloudTec pods and stretches them to cartoonish proportions, promising huge, soft cushioning without turning your stride into a sluggish marshmallow slog. Its one of the boldest shoes in Ons lineup, and, according to many runners on Reddit and review sites, one of the most surprisingly fun.

Meet the On Cloudmonster: A Max-Cushion Shoe That Wants You to Push the Pace

The On Cloudmonster is Ons answer to a very modern problem: how do you protect your joints from endless asphalt while still feeling springy and fast enough to enjoy the run? Instead of a flat slab of foam, On stacks oversized CloudTec elements underfoot and pairs them with a responsive Pebax-based Speedboard plate. The result is a shoe that looks playful but runs seriously well.

Where many max-cushion shoes lean ultra-soft and sleepy, the Cloudmonster is tuned to feel bouncy, not mushy. Runners on forums and Reddit threads consistently describe it with the same word: fun. Its not a razor-thin race flat, but it doesnt pretend to be. This is your daily workhorse for easy runs, long runs, and recovery days that still have a little pop.

Why this specific model?

On makes a full spectrum of running shoes  from the featherlight Cloudboom Echo race shoe to the versatile Cloudflow. So why choose the Cloudmonster over its sleeker siblings?

• Maxed-out CloudTec cushioning: The Cloudmonster uses some of the largest Cloud pods On has ever put into a shoe, combined with a thick layer of Helion superfoam. Ons official specs highlight the huge stack height and soft yet energetic foam formula. In real life, that means your foot lands in a deeply cushioned cradle that still rebounds rather than bottoming out.
• Rockered, rolling ride: The exaggerated rocker geometry is designed to roll you forward from heel to toe. Reviewers often mention how the shoe "wants you to keep going," especially on mid-distance and long runs. That rocker, plus the Speedboard, turns the max cushion into a forward-tipping sensation rather than a squishy mattress.
• Speedboard for snap: Even though this isnt a carbon super shoe, the thermoplastic Speedboard plate inside acts like a flexible spring. When you load it, it pushes back, adding a subtle but noticeable kick during toe-off. Thats why so many runners report that easy runs occasionally "accidentally" become tempo efforts in the Cloudmonster.
• Breathable, structured upper: The engineered mesh upper offers decent structure through the midfoot with enough toe room for swelling on long efforts. Multiple reviewers on Reddit mention that it feels more secure than some earlier On models, with fewer complaints about a narrow fit, though wide-footed runners may still want to try before they buy.
• Durable rubber in the right places: The outsole doesnt try to be a trail shoe, but it has thoughtful rubber coverage under key wear zones. Many owners report 3001500 miles of life, depending on gait and surfaces, which is competitive with other premium trainers from Nike, HOKA, and Saucony.

Translated into everyday terms, the Cloudmonster is that rare running shoe that feels luxurious underfoot but still invites you to pick up the pace on days youre feeling good. If youre training for a half marathon, logging base miles, or simply trying to make sidewalk slogs a little less soul-crushing, this specific model hits a sweet spot between comfort and liveliness.

What Users Are Saying

A quick dive into Reddit threads and running forums shows that the On Cloudmonster has built a strong fan base  but its not without caveats.

The love list:

• "Bouncy and fun" ride: Many runners describe the shoe as playful, using words like "trampoline," "springy," and "surprisingly fast for its size." Its frequently praised for making easy runs feel less like a grind.
• Great for long, easy miles: A recurring theme in user reviews is that the Cloudmonster shines on 5115 mile runs where comfort and protection matter more than outright speed.
• Comfortable upper and step-in feel: Several users note that slipping into the shoe feels plush without being sloppy, with enough room in the toe box for swelling on hot or long runs.
• Versatile beyond running: Some buyers admit they wear the Cloudmonster just as often for all-day standing or walking because of how cushioned and eye-catching it is.

The complaints:

• Not ideal for speedwork or racing: While energetic, the shoes bulk and stack make it less suited for intervals or all-out race days compared with carbon supershoes or lighter trainers.
• Fit can be tricky for wide feet: A subset of users with wider feet report needing to size up or finding the midfoot a bit snug.
• Price point: The Cloudmonster sits firmly in the premium bracket. Some runners feel the cost is justified by comfort and fun factor; others think there are cheaper max-cushion options that come close.
• Outsole in wet conditions: A few runners mention that grip on very wet or smooth surfaces could be better, something to keep in mind if most of your miles are in the rain.

Overall sentiment skews clearly positive: if you know youre buying a max-cushion daily trainer, the Cloudmonster delivers exactly that, with more personality than most.

Behind the shoe is Swiss performance brand On Holding AG, a company listed under ISIN: CH1134540470, which has rapidly grown from niche startup to global running powerhouse on the strength of its CloudTec technology and design-forward approach.

Alternatives vs. On Cloudmonster

The max-cushion category is one of the hottest segments in running shoes right now. Runners are piling on mileage, and brands are responding with thicker, softer, more protective designs. Heres how the Cloudmonster stacks up against some popular alternatives:

• HOKA Bondi: Often considered the archetypal max-cushion shoe, the Bondi is softer and more pillowy but can feel less responsive. If you want a pure plush cruiser, Bondi is tempting. If you want cushion and bounce, Cloudmonster offers more energy.
• Nike Invincible series: Nikes ZoomX foam is ultra-soft and light, with a very squishy feel underfoot. Some runners love that cloudlike sensation; others find it unstable. The Cloudmonster tends to feel slightly firmer, more stable, and more controlled.
• Saucony Triumph: A well-balanced premium trainer that offers a smooth, cushioned ride without the exaggerated looks. The Triumph is a great "do-it-all" daily trainer. The Cloudmonster leans more into personality and punchy rebound.
• On Cloudsurfer: If you want to stay within Ons ecosystem but prefer something a bit lighter and more versatile, the Cloudsurfer is a strong pick. The Cloudmonster, however, wins for sheer underfoot protection and long-run comfort.

If your priority is a soft, stable, and quietly competent daily trainer, one of the alternatives may suit you. If you want a shoe that feels unmistakably different the moment you put it on  and that turns even recovery runs into something a bit more joyful  the On Cloudmonster is in a class of its own.

Final Verdict

The On Cloudmonster isnt subtle. It looks bold, it feels bold, and it fundamentally changes the texture of your daily miles. Instead of bracing for impact with every step, you get a rolling, bouncing stride that invites you to go a little farther than you planned.

Its not the perfect shoe for every scenario. Sprinters and race-obsessed runners will still want a lighter, more aggressive option in their rotation, and wide-footed runners should pay close attention to fit. But for most neutral runners who want a premium, highly cushioned shoe for easy days, long runs, and general road training, the Cloudmonster absolutely lives up to its name.

If your legs have been telling you that your current shoes are too harsh, too flat, or just too boring, this is the kind of upgrade you actually feel from the first step. Lace up the On Cloudmonster, and the pavement stops feeling like punishment  it starts to feel like a playground.
