On the run

Cloudrunner 3: On’s steady, walk-anywhere support shoe. Firm and very stable, with a premium upper and a more rockered ride than before. It lacks bounce, but it’s excellent for easy miles and all-day walking.

Cloudmonster 3: Firm, snappy, unmistakably On. The firmest shoe here in lab tests, with a stiff plate and a rocker that give it a snappy feel at faster paces. It isn’t the shoe for soft recovery runs.

Specs side by side

Stack, drop and weight come from each brand’s own website. Numbers marked * aren’t published by the brand and come from other published specs. Weights are for the size each brand quotes. Expected life is our estimate.

Fit

Cloudrunner 3. True to size with a thick, comfy tongue, but the toebox is narrow. Wide available.

Cloudmonster 3. Snug heel and midfoot. The toebox is narrower than the Cloudmonster 2’s, and it can run a touch long, so if you’re between sizes, try both. Standard width only.
