On Cloudmonster 3 Review: A Responsive, Characterful Daily Trainer
The Cloudmonster 3 layers up the CloudTec design but stays on the responsive side, making it a strong pick for steady-paced road training.
Introduction
The Cloudmonster 3 is On’s latest take on its max-cushion daily trainer, and this version now features a triple layer of the brand’s CloudTec design. It has recently released in the UK and worldwide at around $190, roughly £180 in the UK. After a variety of training runs in it, the shoe comes across as a carefully refined update: slightly sleeker underfoot, more foot-hugging up top, and more responsive than the squishy-cushion trend it sits alongside.
Specs and Sizing
A sample UK 11 came in at around 309 g on the scale, with a measured 333 g on one shoe, which is solid scaling for the size. Forefoot width measured 11.9 cm with 9.4 cm in the heel, giving a slightly sleeker underfoot surface area. The sample stack is listed at 35 mm, though a larger size measured closer to 41 mm at the heel and 36 mm at the forefoot, a 6 mm drop. Low-drop fans should feel at home here.
Upper and Fit
The upper is now a slightly more foot-hugging design and feels improved over the original Cloudmonster. Overlays are minimal and thin, adding little weight, and the laces carry a speckling of reflective material that helps if you run at night. Laces are sensibly sized and secure neatly under a conveniently placed lace garage, a detail more often seen on trail shoes.
The tongue is adequately padded without being overblown, enough to support a runner’s knot, though it could be marginally longer to prevent lace bite. A more traditional heel counter wraps around the back of the foot while still allowing excellent ankle range of motion, and the lace loops feel substantial enough that durability should not be a concern. For narrower feet the fit is on point, and a wider version exists for those who need it. Breathability is fine even in 16 to 17°C temperatures; this is not one of the warmer shoes around.

Midsole and Ride
Where many modern trainers chase maximum softness, the Cloudmonster 3 leans responsive. It is certainly stable, but around steady paces it rewards energy directed into it rather than rewarding easy efforts. The extra layer of CloudTec delivers a characterful compression, and the Helion midsole foam gives a rolling, forward-tipped feel, helped along by the rigidity of the nylon speedboard.
The cushioning is easy to anticipate: rather than your foot simply pressing into foam, each area compresses differently underfoot, dividing the workload like a team. The midsole softens over the first few miles, the CloudTec pods return to form quickly without bottoming out, and the shoe works for almost any foot strike.

Performance and Use Cases
The Cloudmonster 3’s wheelhouse is steady-paced running, including tempo efforts, on road and concrete in urban environments. If you like your shoes responsive and consistent without a squishy feel, this fits the daily trainer role well, especially if you prefer lower-drop, more grounded options over the very soft max-cushion category.
It sits sensibly within On’s own lineup: the Cloudmonster 3 Hyper offers a softer feel with a layer of Helion HF foam underfoot, so this standard version is the pick if you want something a bit more up-tempo. Overall the shoe feels nicely balanced, with weight concentrated low rather than built up around the top.

Outsole and Durability
Rubber depth is generous for an urban shoe, measuring about 4 mm in some areas. Traction is good on bends and curves in dry conditions, and built-in ridges in the rubber should help when routes get damp, though wet-weather performance has not been thoroughly put to the test. Small stones can lodge in the outsole, as with many modern shoes, depending on your local routes. Build quality feels premium and well aligned, and the rubber coverage should last the test of time.

Buying Advice
At around $190, the price leans premium, but the build quality matches it. Choose the Cloudmonster 3 if you want a daily trainer that is responsive, consistent and characterful for steady and tempo-paced road running. If maximum softness is your priority, the Cloudmonster 3 Hyper is the softer alternative within the same family.
Conclusion
The Cloudmonster 3 is a nicely balanced, lower-drop daily trainer that avoids the overly soft feel of much of the current market. With a refined upper, characterful triple-layer CloudTec cushioning, deep outsole rubber and a responsive ride, it is a shoe worth keeping in a regular training rotation.
