Any time you're on your feet is a good time to wear the adidas Ultraboost. These juniors' shoes pack all the performance techs that runners love into a design you'll want to wear outside of gym class. Beyond looks, its superpower is comfort – from the soft feel of the adidas PRIMEKNIT upper to the incredible energy return of BOOST. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic — reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
