The most consequential On shoe of the autumn is not a racer. The Cloudsurfer 3, previewed at The Running Event in Austin last December and now expected to reach shops in a late-September soft launch, is the first shoe from the Swiss brand to put a PEBA-based super foam into its everyday trainer. On calls the material SURREAL and describes it as a fusion of super-foam chemistry with the CloudTec geometry the brand has used since its founding, and it will be sold at $170, or around £160 in the United Kingdom, which places it directly against the Nike Pegasus, Brooks Ghost and ASICS Novablast rather than against the brand's own Cloudmonster Hyper.
The specification is a clear step up from the Cloudsurfer 2. The heel stack rises to 38mm on an 8.6mm drop, and the midsole is claimed to be 20 per cent softer than the outgoing version. Weight is listed at 300g in a men's sample size, which is heavier than some rivals but consistent with a shoe that has added foam volume rather than a plate. The upper is a newly engineered warp knit, a change from the mesh of the previous two generations that the brand says improves lockdown and gives the shoe a more modern silhouette. On has also said the shoe will be the first to carry perforations through a supercritical foam, a detail that speaks to how the company has had to adapt its signature hollow-element look to a material that is not normally moulded that way.
The Cloudsurfer 3 arrives in a season that has been unusually busy for daily trainers. As this site's September release calendar noted, the Nike Pegasus Plus 2 is positioned in the super-trainer space with a curved Air Zoom unit, adidas has the Adios Pro 5 and Diadora launched the Corsa in August. On itself has already released the Cloudmonster 3, the Cloudmonster 3 Hyper and the 45mm, 190g LightSpray Cloudmonster 3 Hyper LS this year, along with the Cloudsoma trail shoe in April. The Cloudsurfer sits below all of those in price and is the model most On customers actually buy, which is why the choice to introduce a new foam here rather than in a limited-run racer matters more commercially than any single launch above it.
There is a broader shift at play. Two years ago, super foams were confined to plated racers priced at $250 and above. In 2026, brands are moving PEBA and supercritical compounds into shoes that will do the bulk of a runner's weekly mileage, and more elite athletes are logging their easy running in unplated trainers such as the adidas Evo SL to protect their legs. The Cloudsurfer 3 is On's answer to that trend, and its 8.6mm drop and 38mm stack suggest a shoe designed for heel strikers and long steady runs rather than tempo work. Early hands-on impressions have not yet been published, and the brand's own preview material stops short of any claim on energy return, so the ride will need to be judged when production pairs are on feet.
For runners deciding whether to wait, the practical question is durability. Softer foams tend to compress faster than conventional EVA, and On's previous Helion compounds have drawn mixed reviews on longevity, so how SURREAL holds up beyond 300 miles will decide whether the Cloudsurfer 3 is a genuine daily trainer or a comfortable shoe for shorter runs. On has not confirmed a firm global release date, and the brand's own calendar guidance has moved before. Running Lookout will publish a review when the shoe is available; until then, the safest assumption is late September in limited colourways, with wider distribution to follow over the autumn.
