On Cloudstratus 3 Review: A Cushioned Workhorse With Trade-offs

Introduction

The On Cloudstratus 3 is On’s big cushioning daily trainer, aimed at runners who want to lace up for long miles in comfort. The previous generation came across as firm and a little unforgiving, so the big question this time is whether On has softened the ride enough to make it a genuine contender in a very crowded daily trainer market. After putting in around fifty miles across a mix of paces on roads and light off-road terrain, the picture is clear: this is a reliable cushioned cruiser, but not a standout.

Key Specs at a Glance

On does not list the stack height for this version, but the Cloudstratus 3 packs roughly 30mm or slightly more in the heel and around 24mm in the forefoot, for a 6mm drop. That is 2mm lower than the previous generation. Weight comes in at 320g (11.3oz) in a UK 8.5, which is 20g heavier than the Cloudstratus 2. Pricing sits at £170 in the UK and $180 in the US.

Design and Build

The midsole uses a double stack of On’s signature Helion foam clouds with a nylon speedboard plate, plus a substantial rocker for stiffness and smooth transitions. Up top, the perforated upper is thin and airy, with plushly padded tongue and heel collar. The gusseted tongue extends deep into the shoe for an almost bootie-like feel, and a fairly rigid external heel clip improves fit security.

Flip the shoe over and there is a generous coating of outsole rubber with pads covering the key cloud elements in all the impact zones, though a fair amount of exposed foam remains around the midfoot.

Fit and Sizing

Both testers ran true to size and recommend sticking with your usual size. The forefoot is very roomy, so runners with narrow feet should take note. The challenge is lockdown: even when laced down firmly, the structured upper resists tightening and the midfoot and heel feel a little loose. One tester reported no heel slip but still found the fit not secure enough for faster running. The enormous heel padding is genuinely comfortable, and long miles were possible straight out of the box, though the shoe took a while to loosen up and always felt noticeable on the foot.

Ride and Performance

The headline change is the midsole. The ride is notably softer and more cushioned than the Cloudstratus 2, with the double-stacked Helion clouds providing good landing protection without feeling overly soft or sinky. If you have always found On shoes too firm, this improves matters, though it still comes up considerably firmer than true pillow-soft rivals like the Asics Gel Nimbus 26 or New Balance 1080 v13.

The rocker helps the shoe clip along, and there is some return and responsiveness, but the Helion foam here feels solid and stable rather than lively. It does not deliver the big bounce of some large-stack daily trainers, and it lacks the more free-flowing feel of On’s own Cloudmonster and Cloud Eclipse, which both perform better in this space. At 320g, the shoe is heavy even by max cushion standards, and you notice it on the foot, which limits its top end and overall versatility.

The outsole is a strong point. Helion is a durable foam, and after around 50k there is very little visible wear. Grip on the sections where rubber is placed is very good, so the sparser rubber coverage does not cause real problems.

Verdict

The Cloudstratus 3 is a reliable, happy cushion cruiser. It makes a decent workhorse for runners content to tick over slower miles, with perhaps a few mid-tempo efforts mixed in, and it is relatively well balanced if a tad heavy. That weightiness caps its speed and daily training versatility, and the firm, stable Helion foam gives little energy back for easy runs or faster efforts.

If you are shopping within On’s range, the Cloud Eclipse, Cloudmonster, and Cloudsurfer 7 all make more convincing picks. Outside the brand, the New Balance 1080 v13 edges it for slow and easy comfort, and the Saucony Ride 17 offers more versatility, with both being cheaper. Compared with the Brooks Glycerin or Saucony Triumph 21, it reads more like an old-school stability workhorse than a true max cushion shoe: your foot sits firmly and supportively, but the midsole delivers little else. At this price, we would choose those alternatives first.

Conclusion

The On Cloudstratus 3 fixes part of the previous generation’s problem by softening the ride, and its durability and outsole grip are genuinely good. But the heavy build, loose midfoot fit, and firm, unresponsive midsole keep it from competing with the best cushioned daily trainers. Buy it only if you specifically want a stable, durable cruiser for easy miles and are happy with On’s firmer foam feel.
