Featuring the biggest CloudTec® ever for massive cushioning and max energy. A monster of a ride on the road. The Cloudmonster is different, that much is obvious. Designed to be the ultimate CloudTec® experience, it propels you forward stride after stride. It's perfect for energizing any run from an easy 5K to a big-effort 20. It may be a playfully weird ride, but it's definitely serious about performance.
