The Adidas Ultraboost was originally conceived as a running shoe, but has now established itself as a casual shoe for everyday wear. Equipped with BOOST technology, it offers high comfort. The Boost sole consists of a thousand compressed EVA balls that store and release energy with every step. This creates a lightness that is further enhanced by the Primeknit upper. The material on the ULTRABOOST 6.0 DNA in "NON DYED" is made from Primeblue, which is made in parts from recycled Parley Ocean plastic. The "Non Dyed" colorway makes it easy to see the structure of the upper.
