Goodbye gravity. adidas designed these adidas Ultraboost running shoes using insights from space. Together with NASA, adidas 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. - Sock-like fit - Lace closure - Textile upper - Textile lining - Boost midsole - Weight: 310 g (size UK 8.5) - Midsole drop: 10 mm (heel: 22 mm / forefoot: 12 mm) - Stretchweb outsole with Continental™ Rubber Shipped by adidas
