Our Verdict

On Cloudmonster 2

On Cloudsurfer Max

The On Cloudmonster 2 and On Cloudsurfer Max are both daily trainers by the same Swiss brand, but pretty different. The Cloudsurfer Max leans into a smoother, firmer, more controlled ride, with its CloudTec Phase design emphasizing a steady roll-through rather than noticeable rebound. The Cloudmonster 2, on the other hand, feels more cushioned and a bit more lively underfoot, and its Speedboard plastic plate gives the shoe more structure and a more driven transition. If you want a smooth, predictable cruiser for everyday miles, the Cloudsurfer Max fits better, but if you want a more cushioned daily trainer with a bit more pop, the Cloudmonster 2 is the stronger pick.
