Crafted with sustainability in mind, the Parley x adidas UltraBoost 21 ‘Non Dyed’ boasts a Primenkit upper that seamlessly blends recycled Parley Ocean Plastic with zero virgin polyester. This eco-friendly design not only prioritizes breathability, but also helps minimize environmental impact. With a focus on performance, this sneaker showcases a lightweight construction that sits atop a full-length Boost midsole, providing unparalleled levels of responsive cushioning. Enhanced energy return is achieved through adidas’ LEP Torsion system, which enhances forefoot stiffness. Additionally, the Stretchweb Continental rubber outsole guarantees optimal traction on various surfaces. Paying homage to its collaboration with Parley, this iteration features Parley branding on both the sockliner and the tongue tag of the left shoe, further cementing its commitment to sustainability and style.
