The UltraBoost 2020 collection by adidas, in collaboration with ISS US National Lab, was specifically crafted for testing in the challenging conditions of outer space, utilizing NASA technologies. This variant, known as the Core Black version, was introduced to the public in December 2019. It features a Primeknit bootie that incorporates strengthened weaves at the toe, along with an enhanced Three-Stripes cage design. The neoprene heel is secured with a 3D frame, and the shoe is completed with a rubber outsole. Notably, the Boost midsole, which offers dual-density support, has been updated with an eye-catching iridescent finish.
