On Cloudultra: For the long and arduous runs
As mentioned, the Cloudultra is primarily intended for ultra-distance running. To be truly effective when tackling long efforts on harsh, gnarly terrain, On made sure to include the following to generate protection and cushion:
- There are two layers of Helion superfoam for a cushy underfoot feel and impact absorption.
- A Speedboard is also integrated into the midsole, which is intended for efficiency. But in the case of the Cloudultra, it's more like a rock plate than a speed-enhancing element.
- Addressing all concerns from past On running shoes, the Cloudultra no longer has channels (deep grooves) on its outsole. This is to prevent rocks and mud from getting stuck and for better multi-surface traction.
Unlike other On shoes: How premium is premium?
The On Cloudultra is the first ultrarunning shoe from the brand that is centered on cushioning and comfort. The shoe borrows the Helion superfoam from the On's road shoes and employs the brand's new FlipRelease system, giving trail runners the option to loosen the shoe's fit as the feet expand after high-mileage efforts.
Lastly, the deep cuts on the outsole, which before, have caused some stone-trapping issues, is a thing of the past in this iteration.
What is it for?
The On Cloudultra really shines in long-distance training on technical trails. As experts claim, its "largest strength" is apparent during ascents. When speeding down steep descents, athletes have found themselves cruising comfortably.
