A lot of the early review noise on the web surrounding the On Cloudmonster 3 has been generally positive, and I can understand why, if you didn't have much experience running with the OG Cloudmonster.
When compared to v2, On has cleaned up the upper, kept the forward-rolling shape, and built a shoe that feels polished, protective, and easy to get along with from the first run.
But after putting my own miles into it, I don’t think this is the exciting update some people are making it out to be.
The original Cloudmonster felt fresh when it landed. It had real personality. It was cushioned, yes, but it also had that snappy, rolling feel that made it genuinely fun to run in, and it performed like a lively bouncy cushioned tempo shoe.

I'm not going to be too harsh, because the Cloudmonster 3 still does a lot right, but for me, it’s lost some of that unique edge. What I’m left with is a solid daily trainer that feels dependable, yet strangely forgettable.

Sizing and fit
Fit is one of the clear improvements here; it no longer has that loose sloppy feel to it.


The Cloudmonster 3 runs true to size for me, with a secure heel and midfoot, plus enough space up front for natural toe splay.
The redesigned upper feels more refined and better dialed-in than previous versions, and the overall hold, and heel-lock is glove-like without feeling restrictive.
My only real nitpick is the tongue, which feels a bit too short and doesn’t rise quite high enough where the laces tie, so I can see some runners noticing pressure there.


Performance review
A smoother, safer ride that lacks the old magic
On’s formula still works in a technical sense. The triple-layer CloudTec, Helion midsole, nylon-blend Speedboard, and rocker combine to create a ride that feels protective, stable, and clearly built to roll you forward.

For easy and steady daily miles, the shoe does its job really well. It absorbs impact nicely, feels planted, and gives you that familiar mechanical pop from the CloudTec pods compressing and rebounding underfoot.
It’s more firm than plush (that may surprise some), and it never feels unstable, which is important in a shoe with a stack height of 35mm and above.
The thing I just keep coming back to though, is this: it just doesn’t feel especially fun, and when there are so many great daily trainers out there, why would you pick this expensive one?

The original Cloudmonster had a spark to it. It felt lively, distinctive, and surprisingly capable when I wanted to push beyond easy pace.
The Cloudmonster 3, by comparison, feels more controlled and more polished, but also more generic. It’s competent. It’s reliable. It rolls along nicely. I just don’t find myself getting excited to lace it up.
Now, the On Cloudmonster 3 Hyper, on the other hand, well, that's a totally different beast; one that runs more like the OG Cloudmonster but with a more stable ride.
If you're looking for the fun Cloudmonster, buy the Hyper instead.

The weight becomes more noticeable than it should
For a shoe with a 35mm / 29mm stack, this feels heavier than I want it to. My pair comes in at 10.6oz (301 g) in a men’s US 9, and that extra heft shows up on the run.
At relaxed paces, it’s manageable enough, especially if all you want is cushion and consistency at a slower pace.

But once I try to pick things up, the shoe starts to feel a bit clompy and blocky underfoot. That’s where the ride loses some of its appeal for me.
Instead of feeling nimble or eager, it feels like I’m working against the shoe more than I should be.
That matters because one of the big selling points of the Cloudmonster line has always been that it can blur the line between daily trainer and uptempo cruiser thanks to the triple layer Cloudtech midsole and Nylon plate.
In this version, I don’t think that crossover magic is as convincing. Yes, it can handle pace changes. Yes, it can move. But it doesn’t feel particularly rewarding when it does.
Firm at easy paces, but still protective
Despite the “monster” branding, this isn’t a deeply soft, sink-in kind of max-cushion ride.

It leans firmer than some runners may expect, especially at easier paces.
That’s not automatically a bad thing. In fact, the firmer tuning helps keep the platform stable and keeps transitions feeling more controlled than sloppy.
There’s decent impact protection here, and I can see why so many other early testers have called it versatile. It never feels harsh, and it has the kind of dependable cushioning that can handle most daily training easily.
Still, if you’re expecting an especially plush cruiser, this isn’t really that. It’s more of a structured, forward-rolling cushion shoe than a soft one, and that difference is worth knowing before you buy.
A strange middle ground in On’s current lineup
This is the bigger issue for me, and it’s what makes the Cloudmonster 3 harder to recommend enthusiastically.
It feels like an overlap shoe.

In On’s current lineup, the Cloudsurfer Max owns the smooth, long-run, high-mileage cruiser role much better, with a more effortless glide.

Then the Cloudmonster 3 Hyper brings more bounce and a more alive underfoot feel if you want that longer-run super-trainer energy.
That leaves the regular Cloudmonster 3 sitting in the middle. It does plenty well, but it no longer feels like the obvious or exciting choice. What used to feel innovative now feels like the safe, sensible option (who wants that? 😋).
For some runners, of course, that will be exactly what they want. There’s value in a shoe that just quietly gets the job done. But for me, this version gives up too much personality in exchange for that safer feel.
Good traction and everyday practicality help it
One area where I do think the shoe deserves credit is overall usability.

The outsole grip is solid on the road, including in wet conditions, and the broader sense of comfort carries over well beyond running. This is the kind of shoe that can handle a run, a long day on your feet, and general everyday wear without feeling out of place.
So while I’m underwhelmed by the ride relative to what this line used to be, I do think it works well as an all-around road shoe for runners who care more about comfort, protection, and predictability than excitement.
My verdict

The On Cloudmonster 3 is a good daily training shoe. It’s comfortable, stable, protective, and noticeably improved in fit. If you want a reliable max-cushion daily trainer with a structured, forward-rolling ride, it absolutely gets the job done.
But I don’t think it’s a particularly memorable one.
The extra weight, the firmer-than-expected ride at easy paces, and the awkward middle-ground positioning in On’s lineup all make it feel less compelling than it should at $190.
It feels like a competent workhorse rather than a shoe I’m genuinely excited to keep reaching for.
If you want safe, solid, and protective, the Cloudmonster 3 makes sense.
If you want a shoe that feels more alive, I’d be looking elsewhere in On’s running shoe lineup first.
