adidas and the ISS US National Lab designed a collection of the UltraBoost 2020 using NASA technologies to test in the extreme conditions of outer space. Unveiled in December 2019, this Core Black version receives a Primeknit bootie engineered with reinforced weaves at the toe and a revamped Three-Stripes cage. A 3D frame is secured to the neoprene heel. Mounted on a rubber outsole, the dual-density Boost midsole is updated with an iridescent finish.
