One of the coolest (and most environmentally-conscious) collaborations continues with the Parley x adidas Ultra Boost. This Ultra Boost features a blue spirit and legend ink primeknit upper, carbon accents on the three stripes cage, and a white boost midsole combined with a Continental rubber outsole. Released in June 2018, this pair retailed for $180. The collaboration is also represented by the Parley x UltraBoost 'Deep Ocean Blue', part of adidas’ 2018 Run for the Oceans campaign, utilizing plastic bottles collected from coastal areas in its construction. This iteration features a near-black colorway inspired by the Mariana Trench and uses the equivalent of eleven plastic bottles, with 85% of the Primeknit upper made from recycled Parley Ocean Plastic.
