About the On Cloudultra 2 Ultra running requires an ultra shoe, and whatever less-travelled path you're running, if you're rocking a pair of the Cloudultra 2 trail trainers you'll be floating on air. The mega cushioning perfect for all-terrain, long-distance running, comes from On's soft Helion™ superfoam that delivers an epic comfy ride on every terrain you'll face. This is complemented by the new Missiongrip™ outsole and updated stud layout, providing 50% more ground contact for enhanced traction on tricky surfaces. Further comfort from the Cloudultra 2 trainer is offered by the knitted sock upper made from 100% recycled polyester, which gives you an oh-so-easy step-in experience. With a more precise fit and durable upper than its predecessor, the On Cloudultra 2 will leave you feeling more sure-footed than ever before, especially with a super-handy TPU Speedboard® that loads with energy every time you land. Chuck in CloudTec® cushioning that protects you against impacts, and you get a seriously supportive, crazy-comfy ride that will eat up any terrain, time and time again.
