Introducing the "4DFWD 2" from Adidas. The Adidas 4DFWD 2 redefines forward motion technology. It combines a unique and innovative 3D-printed midsole with a new upper construction, and features a Continental outsole for enhanced grip. With every stride, the 4DFWD 2's midsole propels your foot forward, reducing the braking force upon landing and converting the impact into propulsion. This creates a smoother stride, unlike the stop-and-go feeling of running on asphalt. Furthermore, the Continental rubber outsole provides grip even on wet surfaces, and the adidas PRIMEKNIT+ upper wraps the foot snugly for a new level of fit, assisting runners in any condition. Although this item is unused, there is damage to the box, and yellowing and discoloration on the sole. Please ask if you have any questions.
