The adidas UltraBoost 2020 is the result of a partnership with NASA's ISS US National Lab initiated to test athletic footwear in space. Unveiled in December 2019, this version is designed with a Primeknit bootie in Dash Grey, ornate toe weaving and a neoprene counter. Its 3D heel frame and Three-Stripes are done in an iridescent finish. The sneaker is supported by a responsive Boost midsole and durable rubber outsole.
