When the adidas Ultraboost debuted back in 2015, it had an impact that spilled beyond the world of running. For this version of the shoes, we retooled the design on a 3D-printed midsole. The denser parts of the lattice provide more support, and the parts that are open feel more cushioned. These shoes don\'t just look like the future. They feel like it, too. adidas Ultra 4D 5 Features: Textile upper Regular fit Lace closure adidas 4D midsole Continental™ Rubber outsole
