The On Women's Cloudultra Trail Running Shoes are ultra-cushioned, ultra-comfortable, and ultra-versatile. For more grip and more fun, a closed-channel construction outsole stops stones from 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. On's revolutionary new FlipRelease™ system makes finding the perfect fit as easy as flipping a switch. The On Women's Cloudultra Trail Running Shoes are made for all-terrain adventure and off-road running.
