Beloved by athletes and sneakerheads alike, the Ultraboost has been a legend since its 2015 debut. These shoes take the genetic code of that original pair — the foot-hugging adidas Primeknit upper and energy-returning Boost midsole — and transform it into a lifestyle shoe made with the future in mind. As a part of adidas' commitment to help end plastic waste, they are made with recycled materials.
