The adidas 4DFWD ‘Core Black Green’ presents a sleek colorway of a running shoe built on 3D-printed tooling. The upper is constructed from black Primeknit with fluorescent green accents on the lace loops, knit collar and adidas-branded tongue tag. Tonal reflective three-stripes reveal an iridescent finish when exposed to high-intensity light. A black 4DWD midsole is engineered to deliver a smooth ride by redirecting vertical force into horizontal forward motion with every stride. Underfoot, a green rubber outsole provides durable traction.
