Parley and adidas have come together previously to forge an Ultra Boost and Pure Boost X out of plastic that was reclaimed from the ocean. Now the eco-friendly colab series continues with the addition of an UltraBOOST Uncaged to the recycled ranks. The white sock-like Primeknit upper of the sneaker is composed of 95 percent post-consumer ocean plastic, while the laces, heel cap and sock liner are made from materials retrieved in the Maldives.

The good news is the Parley x adidas UltraBOOST Uncaged will be the first to go into mass-production – compared to the previous models released in ultra-limited drops. The next round will see 7000 pairs produced initially, with adidas aiming to produce one million pairs by the end of 2017.

The Parley x adidas UltraBOOST Uncaged is expected to drop mid-November via adidas online.
