More energy, more style. The iconic adidas Ultraboost has served up elevated comfort for runners since ‘15. But you don’t have to be a runner to wear them. These shoes bring the same performance technology to the daily realm. BOOST in the midsole charges up every step, and an adidas PRIMEKNIT upper gives feet a soft hug. The rest is all style. 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.
