The road running shoe combining maximum support with a responsive ride, updated for even the most demanding runner. Technology: Packing more Swiss-engineered tech than any other On shoe, the Cloudace is for runners who refuse to compromise. The wide Speedboard® works with the unique CloudTec® configuration so you feel supported but never restricted. For soft, stable landings and our signature explosive push-off. Materials: The step-in sensation is more ace than ever. An extra layer of foam below your foot means instant comfort. Molded side elements then provide a gentle hold. And engineered mesh supports and ventilates exactly where you need it. All of which helps you love your run, from the first stride to the last. Design: It features two different types of CloudTec® for a stable ride with a unique sensation. Rebound Rubber forefoot Clouds feel responsive. Under the heel, Clouds in Helion® superfoam provide no-compromise cushioning. The result is a seriously ace running sensation. Your Sunday long run just got longer. Weight: 335 g Heel-Toe Drop: 9 mm
