Parley and adidas are collaborating once again this time joining forces to create a special iteration of the adidas Ultra Boost 2021. Engulfed in black on the upper, this adidas Ultra Boost 2021 features a Primeknit upper that 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. Additional details include white and blue accents on the side panel overlays, heel counter, and the various branding throughout the shoe. A full-length chunky Boost midsole in white paired up with a rubber outsoles that comes with semi-translucent gum detailing finishes things up on this Parley x adidas Ultra Boost 2021.
