On Cloudsurfer 3 Review: A Big Step Forward for On's Daily Trainer

Introduction

The Cloudsurfer 3 arrives with a meaningful change for the line: for the first time, On has used a supercritical foam in this shoe while keeping its signature CloudTec midsole geometry. That combination has not been easy to engineer. Foam pucks for midsoles start small and expand inside a mold, and getting supercritical foam to fill that mold while preserving the distinctive cutout structure was a problem On had reportedly not solved until now. The result is the best Cloudsurfer yet, though whether it is the right shoe for you depends heavily on fit preference and what you want from a daily trainer.

This review is written from two perspectives: one from a narrow-footed runner who prefers lightweight shoes, and one from a wider-footed runner who values a plush, accommodating fit. Those preferences shape a lot of what follows, and they explain why the verdicts below land differently.

Upper: Plush, Roomy, and Genuinely Comfortable

The upper uses a warp knit construction with a double layer of material. The step-in feel is lovely, with generous padding around the collar, heel, and tongue. It is one of the better On uppers to date, and the fit is accommodating not just through a wide toe box but through the entire throat of the shoe.

There is a trade-off. The upper is thicker than many recent designs, which made it feel a little warm during summer months, though it should be well suited to fall and winter running. Wide-footed runners will appreciate the room and the ability to cinch the laces down well; a heel counter with plenty of padding adds solid lock-down. Narrow-footed runners can go down half a size and still find the fit generous.

Midsole: Supercritical Foam Finally Meets CloudTec

The new foam is called Helion, a supercritical PEBA blend, paired with the CloudTec phase, the term for the cutouts On shapes into its midsoles. The combination delivers a sink-in and bounce-back feel that is bouncy rather than the softest on the market. The underfoot character is comparable to the Brooks Glycerin Max in how it rebounds. Energy return is not quite as high as hoped from a supercritical foam, and the bounce becomes more noticeable the faster you run.

The ride is notable in another way: it feels even and sturdy under the foot, with no lean to either side, almost guidance-like in how it keeps you moving forward. That gives it a subtle stability element that was unexpected in a shoe with CloudTec holes. Stack height is 38mm in the heel and 30mm in the forefoot for an 8mm drop, on a fairly wide platform. Durability looks excellent, with plenty of rubber on the outsole; the PEBA blend leans toward other compounds, and the foam is unlikely to flatten or pack out soon.

Performance: Smooth, Stable, and Better With Miles

Weight is the sticking point. A men’s size 10 comes in at 324g (11.4 oz) and a women’s 7.5 at 8.9 oz (253g), which is on the heavy side for a daily trainer. The shoe also has a somewhat blocky feel on landing, not in the sense of a harsh or unsmooth transition, which it does not have, but in the sense of a very even, sturdy platform.

The other interesting pattern: the more miles put into the shoe, the more enjoyable it becomes, whether that is a break-in period or simply getting used to the underfoot sensation. This is a shoe for easy miles rather than a do-everything daily trainer, and at $170 it sits in a price range where some alternatives feel a bit more versatile.

Who Should Buy the Cloudsurfer 3

If the strengths of this shoe were flipped around, they become real advantages. Runners looking for a stable trainer, a wider fit, more room through the upper, and a firmer, durable midsole will find all of those here. It also has genuine crossover appeal as a casual wear option, in a way that more expensive On models like the Cloudmonster Hyper do not, and it is a massive improvement over the Cloudsurfer 2.

For runners who want a snugger upper, more squish and bounce, a lighter shoe, and a looser ride, the same traits count against it. Design is a strong point, with attractive color palettes expected across the range.

Buying Advice

At $170 and available from September 15th, the Cloudsurfer 3 is a solid daily trainer with a stable, durable, plush-fitting character. If those qualities match what you want from your one daily shoe, it delivers. If you want maximum energy return or a lightweight, narrow fit, there are more exciting options in the same price bracket.

Conclusion

The Cloudsurfer 3 is the best version of this shoe On has made, thanks to the move to supercritical foam and a genuinely comfortable upper. It earns a middling verdict overall: a strong pick for stability-minded and wide-footed runners, and a pass for those chasing lightweight speed.
