Nature has a way of giving you what you need on a run, from fresh air to the hills that give your body (and mind) a challenge. These adidas running shoes celebrate the beauty of our earth. They're made with nature while giving you all the comfort and incredible energy return of the Ultraboost. The foot-hugging adidas PRIMEKNIT upper supports each stride, and the outsole is made of Continental™ Better Rubber. This shoe is made with natural and renewable materials as part of our journey to design out finite resources and help end plastic waste.
