Launched into space for testing by the ISS U.S. National Laboratory, the Ultraboost 20 features a new micro-tuned Boost outsole for superior cushioning and comfort on earth. The collaboration is celebrated across the design of the runners with pop orange details on the Boost midsole and ISS National Lab branding tags on the tongue. The Primeblue upper is crafted using Parley Ocean Plastic to help minimise it's environmental impact. FTP technology and the TPU heel cage deliver a superior fit.
