On Cloudmonster 3: the Swiss brand’s flagship franchise returns stronger than ever

Some models mark a turning point in a brand’s history. For On, the Cloudmonster clearly belongs in that category. Launched in 2022, the first version was an instant hit among runners: protective cushioning, a pronounced forward rocker, and a silhouette unlike anything else on the market. It’s the shoe that established On as a credible—and truly unique—player in the global running scene. With the Cloudmonster 3, the Swiss brand goes back to its roots: a bold rocker, improved dynamism, and the signature CloudTec® cushioning system built from its distinctive “cloud” pods. With refined design and cutting-edge tech, the Cloudmonster series perfectly embodies On’s DNA: one foot in performance, the other in lifestyle. And this time, the family grows with a bold newcomer: the LightSpray Cloudmonster 3 Hyper.

| A third generation blending the best of versions 1 and 2

The Cloudmonster line is built for everyday training. These aren’t On’s fastest carbon-plated race shoes—but they still pack serious performance credentials.

Key ingredients include:
Dual-density Helion™ foam (EVA)
✔ Helion™ HF hyper foam for added rebound
✔ Speedboard® nylon plate
✔ Triple-layer CloudTec® cushioning
✔ Aggressive rocker geometry

For v3, On smartly combines the responsiveness and rocker feel of the original Cloudmonster with the generous cushioning of version 2.

Modern runners want protection to go longer and farther—and more fun in daily miles. The Cloudmonster 3 delivers exactly that.

| Cloudmonster 3: the ultimate fun daily trainer

The standard Cloudmonster 3 is the most accessible model in the range.

It features:
✔ Dual-density Helion™ EVA foam
✔ Triple-layer CloudTec® cushioning
✔ Nylon Speedboard® plate

Visually, the triple CloudTec® stack remains bold and unmistakable. Love it or not, it’s unmistakably On—and its popularity proves the Swiss brand understands both performance and style.

Beyond aesthetics, the outsole geometry has been refined to enhance forward roll. The embedded nylon Speedboard® plate adds propulsion without stiffness overload.

The goal:
➜ Smooth, natural transitions
➜ Added propulsion from the nylon plate
➜ A dynamic yet protective ride

It’s a perfect daily trainer for logging miles, adding light tempo work, and keeping everyday runs enjoyable.

| On Cloudmonster 3 Hyper: built for long runs

The Hyper version targets more experienced runners—those stacking heavy training weeks and preparing for marathons.

Designed to extend distance while preserving the legs, it shines on long runs with added dynamism.

Validated by athletes from the On Athletics Club (OAC), it includes:
✔ 20% more foam
✔ Helion™ HF hyper foam for greater rebound

Notably, there is no plate here—keeping the ride natural and reducing muscular strain over long distances.

If the Cloudmonster 3 is the versatile daily trainer, the Hyper is the ambitious long-run specialist.

| LightSpray Cloudmonster 3 Hyper: the radical super trainer

This is where things get bold.

The LightSpray Cloudmonster 3 Hyper may be the most daring Cloudmonster ever created. Thanks to On’s LightSpray™ upper technology, it becomes one of the lightest super trainers on the market.

Weight matters in performance—and this is a serious engineering achievement.

At just 205 g, it’s the lightest Cloudmonster ever, without compromising comfort.

This sits squarely in the emerging “super trainer” category—bridging the gap between carbon-plated racers and traditional trainers. Ideal for tempo runs and fast long efforts, it’s built to help runners go faster and farther.

Helion™ HF hyper foam delivers protection and explosive energy return, while the LightSpray™ upper keeps weight incredibly low.

| Three models, three clear purposes

On hasn’t multiplied versions randomly. Each shoe has a distinct role:

➜ Cloudmonster 3 → Fun, accessible, versatile daily trainer
➜ Cloudmonster 3 Hyper → Long-run efficiency and muscular freshness
➜ LightSpray Cloudmonster 3 Hyper → Ultra-light super trainer for tempo and extended efforts

All three share the Cloudmonster rocker and CloudTec cushioning—but serve different training needs.

| What really matters

The Cloudmonster 3 represents both a return to roots and a leap forward. More rebound. More fun. A reliable daily companion for stacking miles.

The Hyper version enhances muscle preservation on long sessions and adds extra dynamism for demanding efforts.

The LightSpray pushes the concept to its limit. With 45 mm of ultra-technical foam, 30 km long runs suddenly feel manageable. The only potential drawback? The €290 price tag—placing it among the most expensive shoes on the market.

But quality and innovation are undeniable.

Four years after the original Cloudmonster made waves, On has solidified its place among the industry’s most innovative brands. With this new Cloudmonster 3 lineup, the Swiss brand reinforces its momentum—and aligns perfectly with today’s era of running, where athletes are chasing more speed and more distance than ever before. Cloudmonster 3. Cloudmonster 3 Hyper. LightSpray Cloudmonster 3 Hyper. There’s a Cloudmonster for everyone.

✔ The Cloudmonster 3 will be available on March 5 for €200, the Cloudmonster 3 Hyper will launch on March 19 for €230, and the LightSpray Cloudmonster 3 Hyper will be released exclusively on On.com on March 5 for €290 ahead of its global launch on April 16. All products will be available on On.com.
