On Men's Cloudmonster 3 "Rock/Silver"

The On Cloudmonster 3 arrives with even more of what made it a run club favourite - max cushioning, bold design and a forward-rolling ride that feels energetic from the first step.

This latest iteration introduces a triple-layer CloudTec® cushioning system, delivering increased responsiveness underfoot. Built with Helion™ foam, it balances soft landings with tangible energy return, making daily mileage feel lighter and more dynamic. The enhanced rocker geometry works in tandem with the cushioning and integrated Speedboard® to promote smoother transitions and more powerful toe-offs.

Up top, the engineered knit upper provides targeted breathability zones, while the refined tongue construction improves step-in comfort and midfoot lockdown. Underneath, a compressed rubber outsole optimises traction and durability for consistent road performance.

Max cushioning. More rebound. Forward motion dialled up.
