On Cloud vs Cloudmonster vs Cloudnova — Which One Should You Actually Buy?
Three On shoes that look similar and are built for completely different things. One of them isn't a running shoe at all.
By Azaz Khan · Published August 4, 2026
Quick answer
The On Cloudmonster is the only one of these three built for distance running. The Cloud 5 suits walking, travel and short runs under 5k. The Cloudnova is a lifestyle sneaker and is not designed for running at all, despite appearing in running search results.
Key takeaways
- The Cloudnova is On's streetwear line, not a running shoe, even though it shares the CloudTec sole.
- The Cloudmonster uses Helion superfoam and rocker geometry, making it the only one suited to runs beyond 5k.
- The Cloud 5 is the lightest and most versatile, but most runners feel the lack of cushioning past 5k.
- All On shoes with exposed CloudTec pods collect gravel; this is inherent to the sole design.
- On footwear runs narrow through the midfoot and slightly short, so size up if between sizes.

If you search “On women’s running shoes” you get all three of these on the same page, at similar prices, in near-identical white colourways. They look like variations of one shoe.
They aren’t. One is a max-cushioned distance trainer, one is a light everyday shoe, and one isn’t a running shoe at all.
The short version
| If you… | Buy |
|---|---|
| Run 5k+ regularly | Cloudmonster |
| Walk a lot, run occasionally | Cloud 5 |
| Want an On sneaker for daily wear | Cloudnova |
| Are on your feet at work all day | Cloud 5 or Cloudnova |
The Cloudnova is not a running shoe
This is the single most useful thing to know before you spend money here.
The Cloudnova is On’s lifestyle line. It’s designed for streetwear, and On markets it that way — but because it shares the CloudTec sole design and the naming convention, it ranks in running searches and gets bought by people who then wonder why their runs feel bad.
It’s a good sneaker. It is not a shoe to run in.
Cloud 5 vs Cloudmonster — the real decision
If you’ve ruled out the Cloudnova, this is the actual choice, and it comes down to one question: how far do you run?
The Cloud 5 is the original On silhouette. It’s light, it’s flexible, and it works for walking, travel, gym and short easy runs. Where it struggles is distance — there simply isn’t much foam under your foot, and past about 5k most runners start to feel it.
The Cloudmonster is the opposite. Big stack, Helion superfoam, and a rocker shape that helps you keep turning over when you’re tired. It’s the one to buy if running is the primary use rather than an occasional thing.
The CloudTec pod problem
Worth knowing before you buy any On shoe: the hollow pods on the outsole collect gravel. On road it’s a minor annoyance. On gravel paths or trails it’s constant, and you’ll be digging stones out with a key.
The Cloudmonster’s larger pods are somewhat less prone to it than the Cloud 5’s.
Sizing
On generally runs narrow through the midfoot and slightly short. If you’re between sizes or have wider feet, size up — On’s width options are limited compared to Brooks or New Balance.

Our verdict
Buy the Cloudmonster if you actually run more than 5k — it's the only one of the three with enough cushioning for distance. Buy the Cloud 5 if you want one shoe for walking, travel and the occasional easy run. Don't buy the Cloudnova for running at all; it's a lifestyle sneaker that happens to show up in running searches.
Frequently asked questions
Is the On Cloudnova a running shoe?
No. The Cloudnova is part of On's lifestyle range, designed for everyday and streetwear use. It shares the CloudTec sole design with On's running models, which is why it appears in running searches, but its cushioning is not tuned for repeated impact.
Which On shoe is best for long runs?
The Cloudmonster. It has the highest stack height of the three, uses Helion superfoam, and has a rocker geometry that helps maintain turnover when you tire. The Cloud 5 lacks the cushioning for sustained distance.
Do On shoes run small?
Generally yes. On footwear tends to run slightly short and narrow through the midfoot. If you are between sizes, or have wider feet, size up. On offers fewer width fittings than Brooks or New Balance.
Why do stones get stuck in On shoes?
The CloudTec outsole uses hollow pods that compress on impact. Those openings trap gravel, particularly on unpaved surfaces. It affects every On model with exposed pods and cannot be fixed, only managed.
