On Cloudmonster 3 First Run Review: Comfort First, Speed Second

Introduction

The On Cloud Stratus 3 is the latest version of On’s daily cushioning shoe, built around comfort and reliability rather than speed. It costs £170 or $179.99, weighs 296 grams (10.4 ounces) for men in a size 8, and has a six-millimetre drop. On paper it is a workhorse trainer for easy miles, and after a first run along the river at a relaxed pace, that is exactly what it delivers: a solid, comfortable shoe that ticks the boxes for slower cruising efforts.

The big question is whether that comfort justifies the price, especially with strong competitors in the max-cushion daily trainer space. Here is what the first runs revealed.

Key Features and Specs

The Cloud Stratus 3 keeps the Helion super foam midsole from the previous version but adds a new nylon speedboard designed to promote a smoother transition. The engineered mesh upper gains improved padding around the tongue and heel collar, there is a modest level of outsole rubber for grip and durability, and the toe box is roomy for extra comfort.

Compared with the Cloud Stratus 2, the ride is noticeably softer and more cushioned. The double-stacked Helion clouds provide good protection on landings without feeling too soft or sinky, and the rocker helps roll you through easy miles. If you have always found On shoes a little too firm, this generation changes that for the better without going too far the other way.

Fit and Comfort

Fit is straightforward. The shoe runs true to size for most testers, with plenty of room in the toe box and a heel that feels secure thanks to heavy padding around the tongue and collar. Step-in comfort is excellent, and long miles were logged straight out of the box, though the midsole needed a while to loosen up and felt more natural deeper into the first 10K run.

There are caveats. The shoe is quite roomy through the midfoot and forefoot, so runners with narrow feet may need to lace down firmly to get a locked-in feel. It also runs slightly shorter and snugger than something like the Nike Pegasus, as On shoes generally come up a little smaller, though most runners will not need to size up. Note that the Cloudmonster does require sizing up for some, so it is worth trying both if you are between models.

Ride and Cushioning

On the run, the Cloud Stratus 3 feels plush underfoot while still staying reasonably light. The softness is a step up from earlier On midsoles, closer in feel to the Cloudmonster than older, firmer On shoes, and the landing feels comfortable and stable rather than bouncy.

What it does not have is energy. The foam is not particularly lively, and when the pace picks up, the shoe simply does not want to respond. It is most at home at slower cruising efforts, roughly five-minute kilometres for one marathon-training tester, where it felt stable and protective with no issues at all.

Things to Consider Before Buying

The first consideration is weight. The Cloud Stratus 3 is heavier than many daily trainers and even some max-cushion shoes, and noticeably heavier than the second-generation Cloud Stratus. There is a lot of build to the shoe, so you need to enjoy a big, constructed upper to enjoy these.

The second consideration is price. At £170, this is a lot of money for a shoe designed mainly for slower, comfortable runs. Competitors such as the Brooks Glycerin 20 and Saucony Triumph 21 arguably do what this shoe is trying to do but a bit better, with more versatility, softness, and a touch of bounce, at similar prices. Part of what you are paying for with On is the look, which many runners genuinely like. Finally, On’s newer CloudTec Phase foam, used in the Cloudsurfer, is softer and smoother than the Helion foam here, so that model remains a more lively and agile alternative.

Buying Advice

If you want a cushion cruiser for low-and-slow easy miles, perhaps with a few mid-tempo efforts thrown in, the Cloud Stratus 3 will do the job, just as the Cloud Stratus 2 did. It suits runners logging 5K to 10K comfortable runs, or slow efforts up to a half marathon, who want something solid, stable, and pleasant to wear.

If you are chasing a bouncy, energetic ride or a versatile daily trainer that can handle faster paces, look elsewhere. And if you are already drawn to On, it is worth comparing this against the cheaper Cloudmonster, which offers a softer, more max-cushion feel that some testers still prefer.

Conclusion

The On Cloud Stratus 3 is a solid, comfortable easy-run shoe and a genuine, if modest, improvement on the previous version thanks to the softer ride and new speedboard. It will not blow you away, and its weight and price limit its appeal against strong rivals, but for On fans who want a plush shoe for relaxed miles, it makes a dependable workhorse.
