The adidas Climacool started a running shoe revolution back in the early ’00s with its ventilated design. Then the Ultraboost changed the game in 2015 with its foot-hugging adidas PRIMEKNIT upper and responsive BOOST in the midsole. These shoes mix the two together in a celebration of running heritage, comfort and everyday style. Enjoy.Made with a series of recycled materials, this upper features at least 50% recycled content. This product represents just one of our solutions to help end plastic waste.
