Now in it's second-generation, the On Running Women's Cloudace Running Shoes have raised the bar even higher. This premium road running shoe delivers a high-performance ride with maximum support - perfect for long runs up to ultramarathon distance. Packed with more Swiss-engineered tech than any other On shoe, the Cloudace is designed for the most demanding runner with a re-engineered Speedboard® and the introduction of Helion™ superfoam for even smoother landings. Crafted with a lightweight and breathable engineered mesh upper that supports and ventilates with each stride and an extra layer of foam below your foot delivers instant step-in comfort. Moulded side elements alongside a traditional lacing system ensure a secure fit and a wider shape gives added stability. The Speedboard® works alongside Helion™ superfoam to provide a responsive well-cushioned ride, while two types of CloudTec® keep your feet stable through the gait cycle for a smooth transition. Finally, a re-engineered durable rubber overlay gives even more traction.
