Description INNOVATIVE RUNNING SHOES THAT ARE PART OF OUR SPACE RACE PACK. Goodbye gravity. We designed these adidas Ultraboost running shoes using insights from space. Together with NASA, we ran experiments in gravity to micro-tune Boost midsoles to perform better on earth. And because all the innovation is pointless without thought for the planet, the shoes stand as part of our commitment to help end plastic waste.
