The On Cloudmonster 3 arrives as a fresh update in the daily trainer category. The midsole delivers a plush, well-cushioned feel that absorbs impact beautifully. At 6mm of drop, the transition from heel to toe feels moderate and versatile, accommodating most stride types.
Fit-wise, the Cloudmonster 3 runs true to size with a comfortable, well-structured upper. At $170, it sits at a competitive price point for what it delivers.
The midsole foam holds up well over hundreds of miles, maintaining its cushion and responsiveness long past the break-in period. Overall, the On Cloudmonster 3 is a solid all-rounder that earns its spot in any shoe rotation.
