On-Running says about the Cloudultra
The new lightweight, fully-cushioned training and racing shoe with Helion™. The Cloudultra is the versatile trail shoe made for all-terrain adventure and off-road running. Born in the Swiss Alps, it’s ready to conquer epic mountain mileage, quick bursts through forest glades, rocky routes and gravel paths. And all in total comfort.
For more grip and more fun, a closed-channel construction outsole stops stones catching, while Missiongrip™ provides the traction you need to master mixed terrain. A double layer of Helion™ superfoam works with two layers of CloudTec® to deliver unbeatable cushioning and long-term comfort.
The ultra-breathable two-layer sandwich mesh upper is reinforced with lightweight TPU for durability, while the wrap-fit construction is perforated to ensure total comfort. Our revolutionary new FlipRelease™ system makes finding the perfect fit as easy as flipping a switch.
