On Cloudmonster 3 brings the Swiss brand’s flagship franchise back with a bang

A third generation combining the best of the first two models

The Cloudmonster range is built for everyday training. These are not the fastest shoes in the On lineup, and there is no carbon plate here. What you do get is a concentrated package of technology that makes the range one of the strongest performers in the daily trainer category, including dual-density Helion™ foam (EVA) and even more responsive Helion™ HF Hyper foam.

For version three, the Swiss brand has focused on what worked best in the first two models. This new generation combines the responsiveness and rocker of version one with the generous cushioning of version two. Runners increasingly value shoes with enough protection to go farther and stay on their feet longer. On has clearly understood that, delivering more energy return and, above all, more enjoyment on everyday runs.

Key technologies include:
✔ Dual-density Helion™ foam (EVA)
✔ Helion™ HF Hyper foam
✔ Nylon Speedboard® plate
✔ Triple-layer CloudTec® cushioning underfoot
✔ Aggressive rocker

Cloudmonster 3: the ultimate fun daily trainer

Triple-layer CloudTec® cushioning + dual-density Helion™ foam
The Cloudmonster 3 is designed as an everyday trainer. It is the most accessible shoe in the Cloudmonster range and relies on several technologies:
✔ Dual-density Helion™ foam (EVA)
✔ Triple-layer CloudTec® cushioning
✔ Nylon Speedboard® plate

With its triple layer of CloudTec® underfoot, the design is unlike anything else. You will either love it or hate it. One thing is certain: before On, nothing like this had been seen in running. The success of the model over the past few years shows just how well the Swiss brand understands both fashion and running. But beyond the design, this is first and foremost a very capable running shoe. The lower section has been redesigned to make the rocker more pronounced. For an even more enjoyable ride, a nylon Speedboard sits in the midsole to return energy and provide an extra boost.

The shoe’s goals:
➜ Smooth, natural transitions through the gait cycle
➜ Propulsion from the nylon plate
➜ A lively, protective ride thanks to Helion™ foam and CloudTec® pods

It is an ideal daily trainer for stacking up the miles, adding some tempo work depending on your level and having fun on everyday runs.

Cloudmonster 3 Hyper: built for long runs

This is a step upmarket, aimed at more experienced runners: athletes handling big training weeks and preparing for a marathon. The Cloudmonster 3 Hyper is an ideal training shoe for them. Designed to make distance feel more manageable, it should excel on long runs, helping preserve the legs from muscular fatigue while maintaining an impressively lively ride.

This new model, tested and approved by the elite athletes of the On Athletics Club (OAC), features:
✔ 20% more foam
✔ More responsive Helion™ HF Hyper foam

The shoe was designed without a plate to keep the stride natural and spare the legs the stiffness a plate can bring. If the Cloudmonster 3 is the versatile trainer, the Hyper is the more ambitious option for faster long runs.

LightSpray Cloudmonster 3 Hyper: a radical super trainer

The range steps up again with a shoe that elite and experienced runners are likely to love. The LightSpray Cloudmonster 3 Hyper is arguably the boldest Cloudmonster ever made. Thanks to its LightSpray™ upper technology, On has produced one of the lightest super trainers on the market. Given how much weight matters to performance, that is an impressive technical achievement. Put simply, this is the lightest Cloudmonster ever produced, with no compromise on comfort.

This is a training super trainer, part of the new category positioned between carbon-plated racing shoes and traditional trainers. The LightSpray Cloudmonster 3 Hyper is made for tempo runs and fast long runs. Its aim is straightforward: run faster and longer. Helion™ HF Hyper foam delivers protective cushioning and substantial energy return, while the LightSpray™ upper brings the weight down to just 205 grams.

A clear message: three shoes for three distinct uses

What is interesting is that On is not multiplying models without purpose. Each of these three shoes has a clearly defined role:
➜ Cloudmonster 3 → Fun, versatile and accessible daily trainer
➜ Cloudmonster 3 Hyper → Long runs and lively recovery runs
➜ LightSpray Cloudmonster 3 Hyper → Ultralight super trainer, ideal for long runs and tempo sessions

The Cloudmonster rocker and CloudTec cushioning run through the entire range, but each model has a distinct mission.

The key takeaways

The Cloudmonster 3 is both a return to the roots and a leap into the future. More bounce, more fun. It is the accessible, dependable shoe for stacking up everyday miles. The Hyper helps keep the legs fresher on long runs while adding even more responsiveness for tougher paces and greater distances.

The LightSpray shows how far On can push the Cloudmonster concept. It is a shoe from the future, designed for runners who want to go faster and farther. With 45 mm of highly technical foam underfoot, 30 km long runs no longer look intimidating. The price may give some runners pause, though. At €290, the pair sits among the most expensive on the market. What is certain is that the quality is there, as usual with On. This is a major strategic launch for the Swiss brand, and probably one of the most important releases on its 2026 calendar.
