We already knew that adidas had a joint release with Parley for the Oceans this season, a sneaker collab centering around the slip-on NMD_CS1. It turns out the partner brands were working on a second silhouette as well, the UltraBOOST ST, done up with a Primeknit upper made in part with Parley Ocean Plastic, which is recycled waste gathered from beaches and coastal communities before it reaches the ocean. The lightweight runner also features a molded heel counter and an engineered knit cage for midfoot stability, as well as signature BOOST cushioning underfoot.

The kicks are available now at adidas.com.
