To explore performance footwear in space, adidas designed a six-piece collection of the UltraBoost 2020 with assistance from NASA's ISS US National Lab. This iteration—launched in December 2019—captures the re-engineered Primeknit bootie in black with reinforcing weaves at the toe and neoprene heel. An iridescent blue finish updates the 3D counter frame and Three-Stripes on the midfoot cage. The sneaker tools a dual-density Boost midsole and rubber outsole.
