They are less than 10 years old and are already a legend. Of course we are talking about Ultraboosts. The design that changed the concept of comfort in running quickly conquered its place even in the wardrobe of every sneakerhead. This version celebrates an iconic silhouette by highlighting its essentials, adidas PRIMEKNIT upper and energy-returning BOOST midsole. The upper is made using a high-performance recycled yarn that contains at least 50% of Parley Ocean Plastic, a material born from the creative reuse of plastic waste recovered on islands, beaches and coastal communities before they can reach the oceans. The other 50% of the yarn is recycled polyester.
