Making its debut in partnership with the International Space Station's U.S. National Lab, the Ultra Boost 20 boasts adidas' all-new Tailored Fibre Placement Primeknit uppers. This means reinforcements are stitched in at key stress points for heightened support. A stripped back heel cage saves weight and provides heightened support to your Achilles, and as expected, a Boost midsole underfoot provides you with energy-returning cushioning that propels you forward. They're signed off with co-branding at the tongue and a space-age iridescent effect across the midsole - EG1341, Textile & Synthetic Upper/Synthetic Sole.
