As a rule I’m skeptical of big brands “going green,” but it seems adidas might just be on to something. Recently the sporty retail giant teamed up with Parley for the Oceans—an idealistic group of “creators, thinkers and leaders” attempting to re-purpose the ocean’s overwhelming amount of trash into reusable material—for a mystery project. Monday at the United Nations the brand unveiled their collaboration: the world's first ever shoe upper made solely from harvested ocean plastic and illegal deep-sea gillnets. The nets were retrieved after a 110-day expedition by Parley partner organization Sea Shepherd, where they tracked an illegal poaching vessel off the coast of West Africa.
