The partnership was research rather than a marketing line. adidas sent Boost material to the International Space Station's US National Laboratory on a cargo mission, where the moulding process could be observed without gravity pulling the beads into a settled arrangement, a test that is impossible to run on the ground.
The shoe itself was a substantial revision. adidas added around twenty percent more Boost than the first-generation UltraBoost carried, reworked the heel counter, and kept the Stretchweb outsole and Torsion Spring underneath.
It launched globally in December 2019, and the space framing carried through the following year's colorways. The Explorer treatment sits in that run, reaching for the theme through silver and metallic detailing over a white Primeknit upper rather than through any literal graphic.
