The On Cloudmonster is On’s most cushioned shoe. Oversized CloudTec® pods give it a tall, bouncy, soft ride that makes long walks, easy runs and long days on your feet feel easier. Shop the Cloudmonster in bold and neutral colorways, or browse more men’s On and women’s On.

What Makes the Cloudmonster Different

Every On shoe uses CloudTec®, hollow pods in the sole that compress when you land and firm up as you push off. The Cloudmonster takes that idea to the max with bigger pods for extra cushioning and bounce.

Who the Cloudmonster Is For

• Easy runs and long runs: If you want maximum cushioning for comfortable miles, the Cloudmonster is one of On’s top picks.
• Long walks: The soft, bouncy ride keeps you comfortable for hours.
• All-day wear: A great choice if you spend long days on your feet and want plenty of cushioning.

Cloudmonster Sizing and Fit

Most people wear their usual size in On shoes. Many On models have a snug midfoot, so if you have wide feet or are between sizes, consider going up a half size. If you’re coming from Nike running shoes that feel tight, try a half size up. For running, leave about a thumb’s width of room at the toe, since feet swell on longer runs.
