The On Cloudmonster 3 Hyper is a max-cushion trainer with a top layer of Helion HF PEBA foam, paired with a firmer EVA-based lower layer with pods to preserve the stable, predictable ride that defines the brand. On brings major changes to this second iteration* by raising the stack, adding more Helion HF cushioning, and creating a much more cohesive ride from heel to toe instead of the more contrasted feel of the original. This very cushioned shoe is a strong option for long runs and for runners who want a highly protective ride that still feels very smooth.
* Curiously, On jumped straight from the original On Cloudmonster Hyper to this one, without making a Cloudmonster 2 Hyper shoe.
Our Verdict
The On Cloudmonster 3 Hyper is designed as a training shoe rather than a true marathon racer, but it's still a decent option for marathon-distance efforts if you aren't aiming for especially fast paces. The shoe is quite heavy, so it feels a bit clunky underfoot. On the plus side, its very protective cushioning and stable platform work well over long distances, making it better suited to runners who want a cushioned, unplated ride focused more on smoothness and consistency than outright speed.
Stable platform due to the bottom carrier layer.
Top layer of PEBA adds some bounce, especially upfront.
Too bulky for efficient racing.
No plate.
The On Cloudmonster 3 Hyper isn't well-suited to 5K and 10K racing. It feels too bulky and not snappy enough for shorter, faster efforts, and the combination of its weight, unplated design, and only moderate pop makes quick turnover harder than in more purpose-built racers.
Too bulky for efficient racing.
No plate.
The On Cloudmonster 3 Hyper has a moderately bouncy midsole, thanks to its full-length top layer of PEBA-based Helion HF sitting over a firmer EVA bottom layer. That setup gives the shoe a pleasant rebound and keeps it from feeling flat, but the more controlled character of the carrier foam means the shoe doesn't deliver the especially springy, explosive sensation of the most energetic performance trainers.
Top layer of PEBA adds some bounce, especially upfront.
Heel rebound is less lively than the forefoot.
The On Cloudmonster 3 Hyper is amazingly cushioned, with especially strong protection under the forefoot. It does a great job absorbing impact and staying comfortable deep into longer runs, making it a strong option for high-mileage training, easy long runs, and runners who want a very protective ride without something that feels overly mushy.
Very protective cushioning, especially at the forefoot.
The On Cloudmonster 3 Hyper delivers solid lateral stability for a tall max-cushion shoe. Its broad platform and planted base make it more controlled and predictable than many high-stack trainers. The firmer bottom layer helps offset the softer top layer, creating a much more stable ride than it might initially suggest.
Stable platform due to the bottom carrier layer.
The On Cloudmonster 3 Hyper fits true to size overall, with accurate length and a comfortably accommodating shape through the forefoot and arch. The only minor drawback is that the forefoot height is less generous, so runners with higher-volume feet may feel a bit more pressure over the top of the toes.

Differences Between Sizes And Variants
We tested the On Cloudmonster 3 Hyper in men's US size 9, as noted on the label for our pair. Our pair is the Lily/Limelight colorway. This model is also available in several other colorways, including Black/Ivory and Glacier/Black, though availability can vary by region and retailer. There are no wide versions offered. The design section applies only to the exact pair we tested, but we expect other sizes and gender variants to perform similarly. There's also a LightSpray™ version with a sprayed-on upper, but we haven't tested this variant, so our results only apply to the standard version.
Popular Running Shoe Comparisons
The On Cloudmonster 3 Hyper is a max-cushion daily trainer that competes in the growing class of highly cushioned, premium unplated shoes, and after a few recent On releases that felt more like hype than substance, this one changes that perception. Some recent models from the brand nailed certain elements without ever feeling truly complete, but this one brings the best parts together. It has the PEBA-based foam that made the On Cloudboom Zone feel lively, but in a package with even more stack and cushioning than their flagship super shoe, the On Cloudboom Strike. The result is a highly cushioned trainer that delivers a noticeably smoother and more premium experience than its smaller sibling, the On Cloudmonster 3.
Yet the firmer bottom layer keeps it from becoming overly chaotic, which makes it reminiscent of the ASICS SUPERBLAST 2, even if the ASICS is lighter and feels a bit more effortless when picking up the pace. This is one of On's most well-executed daily trainers, and the inclusion of a premium foam in an everyday model reflects a shift in mindset for the brand. As more runners have realized that the Swiss-cheese-like CloudTec pods don't magically result in more cushioning on their own, On leans on a more conventional top layer of high-quality foam, and the result is a midsole that absorbs a similar amount of impact to the Brooks Glycerin Max 2. The CloudTec remains in the firmer bottom layer, where it finally feels like it has found its proper role, helping deliver a ride that is cushioned, forgiving, and much more cohesive.

The On Cloudmonster 3 Hyper and ASICS SUPERBLAST 3 are both unplated, max-cushion shoes built around energetic foams, but they push that concept to different extremes. The ASICS is more cushioned, bouncier, and lighter, which makes it more efficient and better suited to picking up the pace, largely due to its A-TPU-based setup. The On follows a similar idea but in a more restrained way, feeling more conventional and more predictable underfoot, with its PEBA top layer not reaching the same level of bounce or efficiency.
The On Cloudmonster 3 Hyper and Saucony Endorphin Azura are both plateless, cushioned shoes, but they target different parts of a rotation. The On leans more into cushioning with a taller stack height, creating a more protective, comfort-first ride that's better suited to recovery runs and relaxed mileage, though it can feel a bit more cumbersome. The Saucony is lighter and more versatile, with a more energetic PWRRUN PB midsole that makes it easier to pick up the pace and handle a wider range of efforts.
The On Cloudmonster 3 Hyper and On Cloudmonster Hyper share the same concept, but the newer version significantly improves the ride. Curiously, there is no Cloudmonster 2 Hyper, as the brand jumped directly to the 3 Hyper. The Cloudmonster Hyper uses a more simplified setup, with Helion HF focused primarily in the forefoot, which makes it feel more forefoot-dominant and closer to a straightforward, speed-oriented trainer. The Cloudmonster 3 Hyper moves to a more complete construction, adding a full top layer of PEBA over an EVA base, which results in a more cushioned, more energetic ride with a higher stack while staying in a similar weight range.
The On Cloudmonster 3 Hyper is the lighter, more energetic sibling of the On Cloudmonster 3, which is a stable, neutral daily trainer. The Hyper is higher stacked, has a more premium, PEBA-based Helion HF foam, and most of the holes in its midsole are decorative and don't go all the way through. That gives the Hyper far better cushioning and drastically more energy return, all while weighing over 30 g less. The normal Cloudmonster 3 is firmer and more stable, so it will appeal more to runners who want a more grounded ride.
We buy and test running shoes with a very data-oriented approach. While we're just getting started, our methodology already has dozens of tests to help you make the right purchasing decision for your needs. Not only do we use high-end equipment to gather objective data, but we also order multiple sizes of the same shoes so team members can log in miles. This real-world testing is conducted at various paces and conditions, across different types of workouts, to cover all the bases. This allows us to verify our results and ensure they align with what you might feel with a specific pair.
