Parley for the Oceans and adidas continue their ongoing partnership by unveiling a duo of sustainable takes of the UltraBOOST 21 and Adizero silhouettes.The two brands — who have also teamed up for a ZX8000 — linked for an eco-friendly UltraBOOST 21 last year and now return to the performance sneaker for another run. Equipped with the comfort associated with the traditional UltraBOOST, this sustainable iteration features a PRIMEKNIT upper made from Parley Ocean Plastic and recycled polyester, which sits atop an energy-returning BOOST midsole.Arriving alongside the UB21 is the lightweight Parley x Adizero. Housing all the features that gives the silhouette its reputation as a speed-focused shoe (most notably the Lightstrike cushioning underfoot), the Adizero is made with a significantly lower footprint than previous versions, with up to 60% less emissions per pair.Both the UltraBOOST 21 and Adizero look set to drop on May 1 and will be available via the adidas Australia webstore.In other footwear news, JJJJound has teamed up with ASICS for a duo of GEL-KAYANO 14 collaborations.Click here to view full gallery at HYPEBEAST
