n addition to the “Football Blue” colorway, the NASA x adidas Ultra Boost DNA is offered in a sleek “Halo Silver” finish. With the model essentially honoring the National Aeronautics and Space Administration, the tonal silver theme may be inspired by spacesuits or the International Space Station. Finally, semi-translucent grey lace caging, silver TPU heel overlays, white Boost midsoles, and NASA branding on the insoles and tongues round out the design.
