Plus CloudTec cushioning to absorb impact. So you can keep racking up the miles with confidence.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.)
