Story Cloud-like cushioning for more comfortable long runs While there’s no such thing as an effortless long run, the On Cloudsurfer Max brings you as close as you can get. Through a double layer of CloudTec Phase™ and Helion™ superfoam, these runners absorb most of the impact while delivering incredibly smooth heel-to-toe transitions. Their rubber-padded outsole enhances traction, and a light mesh upper keeps your feet cool—while a knitted tongue, flat knit collar, and next-generation eyestays keep your fit secure. Together, you’ve got everything you need to rack up the miles.

And we’ve followed them the whole way—even spending quality time at their HQ at the base of the Swiss Alps. Their team is led by triathlon champ Olivier Bernhard, and every product is tested by Olympians, triathletes, and every other stripe of competitor.
