The On Cloudmonster is the most polarizing daily trainer I have tested in 2026. After four months and 280 miles on asphalt and finished bike paths, the Cloudmonster has earned a slot in my rotation as the shoe I wear when I want something different from a standard cushioned trainer. The oversized CloudTec elements give a landing feel unlike any other shoe in this price bracket, and the Speedboard plate adds real propulsion at tempo pace.
Why you should trust this review
I purchased this pair at retail in December 2025 from On’s site. On did not provide a sample and had no editorial input. I have run in the On Cloudsurfer and the Cloud X 3 over the past two years, so I can speak to where the Cloudmonster fits in On’s lineup.
How we tested the Cloudmonster
- 280 miles across 52 hours of running between December 2025 and April 2026.
- Paces from 9:30 per mile easy to 6:50 per mile tempo segments.
- Surfaces: asphalt road, concrete sidewalk, finished bike path. Avoided gravel after the first run.
- Temperature range: 24 F to 72 F.
- Comparison runs with the Cloudsurfer and the Nike Pegasus 41.
Our running-shoe protocol is on our methodology page.
Who should buy the Cloudmonster
Buy if you have run in On shoes before and liked the CloudTec feel, you want a distinctive ride for daily training, and you primarily run on paved surfaces. Skip if you prefer a traditional cushioned ride, you weigh under 130 pounds and want a lighter shoe, or you frequently run on gravel.
Cushioning: the CloudTec experience
The oversized CloudTec elements at the heel and forefoot give a landing feel unlike any other trainer. The cushion is firm at the very top of the stride and then compresses through the CloudTec pods. The result feels both soft and springy. On 8 mile easy runs at 9:00 per mile, the ride is unique and comfortable. On 4 mile tempo segments at 7:00 per mile, the Speedboard plate adds noticeable propulsion.
Energy return
The Speedboard plate is a flexible plastic insert that runs through the midsole. It is not a carbon plate and does not have the same propulsion as a super-shoe, but it adds meaningful rebound at faster paces. The Helion superfoam still feels responsive at 280 miles in my test pair.
Fit and lockdown
The engineered mesh upper holds the midfoot well. The heel cup is shaped firmly and prevented heel slippage on every test run. The toe box is slightly narrower than the Pegasus 41 or the 1080 v14, which is the only fit complaint. If you have wide feet, sizing up half a size helps.
Weight: the elephant in the room
At 322 g per shoe, the Cloudmonster is the heaviest trainer in this comparison set. It is 36 g heavier than the Nike Pegasus 41 per shoe. The weight is noticeable on tempo runs and in the final miles of a long run. If you prioritize weight, the Pegasus 41 or the Saucony Endorphin Speed 4 is a faster option at this price.
Durability
The rubber-coated CloudTec pods show even wear at 280 miles. The lateral heel is the heaviest wear point. The Helion foam still has spring. The one durability concern is small stones lodging in the CloudTec elements on gravel, which can cause uneven wear if not picked out.
Value
At $170 the On Cloudmonster is the right Shoes in 2026.

Frequently asked questions
Is the On Cloudmonster worth $170 in 2026?+
If you have run in the shoe and like the unique CloudTec feel, yes. If you have not tried On before, try a pair in store before buying. The Cloudmonster is more expensive and heavier than the Pegasus 41 or Ghost 16, and the appeal is the distinctive ride rather than pure performance.
Cloudmonster vs Cloudmonster 2: which is better?+
The Cloudmonster 2 came out in late 2025 with a refined upper. The original Cloudmonster remains widely available at occasionally lower prices. Both rides feel similar. If you find the original at a discount, it is the better value.
Are the CloudTec holes a problem on trails or gravel?+
Yes on gravel paths. Small stones lodge in the CloudTec pods and need to be picked out after the run. On asphalt and concrete, this is not an issue. Avoid using the Cloudmonster on gravel-heavy routes.
How long does the Cloudmonster last?+
Plan on 350 to 450 miles. Our pair at 280 miles still feels responsive with no notable foam compression. The rubber coating on the CloudTec pods is the wear point, and uneven wear can develop if you have a strong pronation pattern.
Does the Cloudmonster run true to size?+
True to size for most. The toe box is slightly narrower than the Pegasus 41. If you have wide feet, try a half size up or look at the New Balance 1080 v14 in 2E width instead.
