Our Verdict
On Cloudmonster 2
On Cloudsurfer 2
The On Cloudsurfer 2 and the On Cloudmonster 2 offer two distinct experiences within On's daily training lineup. The Cloudsurfer 2 is a classic daily trainer, with a moderate stack height, lighter weight, and an early-stage rocker that promotes smooth transitions at easier paces. Its firm underfoot emphasizes ground feel and control over plushness or bounce. The Cloudmonster 2, on the other hand, is On's maximalist option—higher stacked, more cushioned, and noticeably more energetic thanks to a more responsive midsole. While both shoes are on the firmer side overall, the Cloudmonster 2 feels slightly softer and more forgiving.
