ULTRABOOST SHOES WITH REFLECTIVE DETAILS. The race to end plastic waste is a long one. But these Ultraboost shoes belong somewhere near the starting line. For this version, we add some shine with reflective details on the toe. The adidas Primeknit upper has the same weave featured on the original design dropped back in 2015. Boost provides incredible energy return, whether you wear them while running or as an everyday pair.
