Just like you rely on the ground beneath your feet to keep you moving forward, it relies on you too. Show up for the earth, and yourself, in these adidas by Stella McCartney Ultraboost X Shoes. Turning pollution into performance, they're made with Primeblue, a performance recycled material made using upcycled plastic waste collected from beaches and coastal regions. They're also made with Boost cushioning, which means that when you feel like you're lacking energy during that final push, the plush midsole helps you find it.nnBut these aren't just about speed. There are different kinds of paces and modes, and the sophisticated, slip-on silhouette keeps you cruising through them all. Just like they go anywhere, they go with everything. Keep things casual, or dress it up. Ball gown at brunch? Why not. Sit down and surprise them with these as they peek out beneath your hem.
