The Cloudmonster 3 is On's best-known trainer relaunched: a triple-layer CloudTec cushioning system under an aggressively curved rocker, with a nylon-blend Speedboard giving the pop the original was loved for and the 2 was accused of losing. It stays a big shoe at about 295 g.
It suits you if your daily shoe should be fun — easy miles and long runs that roll forward on their own, in the shoe that made On's max-cushion reputation.
It is not subtle, and the rocker has opinions about how you land; runners who want their cushioning quiet should look at the Cloudsurfer Max instead. At $190 it also costs like the statement shoe it is.
