Description
adidas’ Ultraboost evolves as each year passes, with newer, more innovative models that push the boundaries of sneaker innovation. The latest, named the Ultraboost 21, might be the most progressive yet. The Primeknit uppers, for example, are part recycled using ocean waste, while its boost™ cushioning — which is chunkier and more energy giving — is teamed with a new Torsion system for increased responsiveness.
