The adidas Ultra 4D 5.0 "Carbon" delivers a monotone take on a performance runner built on the brand's revolutionary 3D-printed midsole, featuring a unique lattice structure crafted from a blend of light, oxygen and liquid resin. Up top, breathable Primeknit weaves together black and grey fibers to create unique patterns around the toe box and collar. Three-stripe branding is integrated into the midfoot cage, which works in tandem with a molded heel counter to provide added stability and support.
