The Ultraboost was a game-changing runner on its debut, but adidas is never satisfied when it comes to performance tech. There’s always something to tweak, develop, or replace entirely. In the case of the Ultra 4D, it’s the midsole. It’s digitally printed in a unique lattice structure that’s dense where you need more support and more open where you’d benefit from extra cushioning. The flexible Primeknit upper and lace caging is taken straight from the regular Ultraboost, though — black, white and almost pixelated on this pair, to further the futuristic aesthetic. - Primeknit Uppers - Sock-Like Construction - 4D Midsole - Rubber Outsole - Style Code: G58158
