Nonprofit organization Parley teamed up with adidas to continue their expansive collection aimed at raising awareness about the dangers of plastics in the ocean. The Parley x UltraBoost 4.0 features a recycled ocean plastic upper dressed in Carbon Blue and white, with a black TPU cage on the Three-Stripes branding for added structure. The sneaker also sports Parley branding on the tongue, while cushioning arrives via a full-length Boost midsole. A white Continental rubber outsole provides traction.
