The adidas Ultra 4D ‘Black Sonic Ink’ showcases a two-tone palette on a hybrid running shoe that pairs the familiar silhouette of the UltraBoost with a lattice-like 4D midsole. Made with 50% recycled content, the sock-like textile knit upper features a distinctive woven pattern in black and blue. The latter color is repeated on the molded midfoot cage and external heel counter, both rendered in a subtle iridescent finish. Precisely coded cushioning arrives via adidas’ revolutionary 3D-printed midsole.
