This On Cloudmonster 3 review covers the updated version of On's flagship max-cushion shoe. It costs about $190 at full price, weighs 10.4 oz in the men's and adds a three-layer CloudTec system and a TPU Speedboard. Reviewers say it has a forward-rolling feel and strong forefoot shock absorption, but it is heavy, firm and expensive. Our research also found the older Cloudmonster 2 on deep discount. Best for: runners who like On's rocking ride and want max stack for long runs.

Fit and sizing
RunRepeat's 32 owner votes call the Cloudmonster 3 true to size. On offers Narrow, Normal and Wide in the men's and Normal and Wide in the women's, per RunRepeat. Lab data found a mid-sized toebox. Our running shoe finder can filter by width.
Cushioning and ride
On lists a 40 mm heel and 34 mm forefoot stack with a 6 mm drop. The Helion foam with a three-layer CloudTec and TPU Speedboard gives a rolling feel. RunRepeat measured it among the firmest foam readings it has recorded, so expect a firm, bouncy-feeling platform, not a squishy one.
How it performs for long easy runs
Reviewers say the shoe excels on long runs and in daily wear, and doubles as a sneaker. It is a heavy shoe, so it isn't meant for tempo. Our cushioned running shoes list compares other options.
Price and value
At about $190 at full price, RunRepeat says the high price hurts the overall value. The Cloudmonster 2 is often discounted and may be the better deal.
Alternatives
The HOKA Bondi 9 and Brooks Glycerin 23 offer more traditional soft cushion for less. The On Cloudsurfer 2 is lighter. See the On brand page.
Who should skip it
Skip the Cloudmonster 3 if you want a soft ride, a light shoe or a budget price.
