On Women's Cloudmonster 3 "Frost/Ivory"

The On Cloudmonster 3 returns with even more of what has made it a favourite among everyday runners: maximum cushioning, energetic rebound and a smooth, forward-rolling ride. Designed for runners who want comfort without sacrificing responsiveness, it's built to make every mile feel lighter, softer and more efficient.

At the heart of the Cloudmonster 3 is an updated triple-layer CloudTec® cushioning system, delivering even greater impact absorption and responsiveness than previous generations. Constructed from lightweight Helion™ foam, the midsole provides plush landings while returning energy with every stride, creating a ride that remains lively from the first kilometre to the last.

Working in harmony with the cushioning, On's signature Speedboard® promotes efficient energy transfer through each transition, while an enhanced rocker geometry encourages smooth heel-to-toe movement and powerful toe-offs. The result is a highly cushioned daily trainer that feels surprisingly quick when the pace begins to rise.

The engineered knit upper features targeted ventilation zones for breathable comfort, while an updated tongue construction improves step-in feel and secures the midfoot for a more confident fit. Underfoot, a compressed rubber outsole delivers reliable grip and durability, standing up to the demands of everyday road running.

Whether you're building weekly mileage, heading out for recovery runs or simply looking for premium comfort on every outing, the Cloudmonster 3 delivers one of On's most energetic and highly cushioned running experiences.
