From toe to heel, each element of the Cloudrunner 2 is designed to support your foot during movement. A plush tongue means total comfort and easy step-in, while a durable heel clip helps to lock in extra stability and support. (And say goodbye to trapped stones, thanks to an updated outsole.) For the Cloudrunner 2, the tech upgrades don’t stop at comfort and performance. This next-gen style features a mesh upper made with recycled polyester.
