The adidas Ultra 4D 5.0 ‘Black Solar Red’ showcases a two-tone palette on a running shoe that combines bleeding-edge technology with a sustainable build. The black and grey knit upper features Primeblue construction, made up of high-performance recycled materials that include Parley Ocean Plastic. Contrasting pops of Solar Red distinguish the midfoot cage, external heel counter and interior lining. The lightweight assemblage rides on a groundbreaking Ultra 4D midsole, crafted from a blend of light, oxygen and liquid resin. New with tags.
