With their soft tones, these adidas Ultraboost shoes make a stylish addition to your running kit. They promise a smooth ride too. The sock-like adidas PRIMEKNIT upper supports the foot while letting air flow. BOOST cushioning gives you incredible energy return and the Stretchweb outsole flexes to match your stride. Made with grippy Continental™ Rubber, it helps you stay planted. 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.
