They are under 10 and are already a legend. Obviously we are talking about ultraboost. The design that changed the concept of comfort in running has quickly conquered its place in the closet of each sneakerhead. This version celebrates an iconic silhouette highlighting its essential elements, the URA Adidas Primeknit and the Boost in the return of energy. 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 at the coastal communities before they can reach the oceans. The other 50% of the yarn is in recycled polyester.
