The race to end plastic waste is a long one. But these Ultraboost shoes belong somewhere near the starting line. This version radiates with a solar yellow upper. The adidas Primeknit has the same weave featured on the original design dropped back in 2015. Boost provides incredible energy return, whether you wear the trainers while running or as an everyday pair.
