More Air, less bulk. The Dn8 takes our Dynamic Air system and condenses it into a sleek, low-profile package. Powered by eight pressurized Air tubes, it gives you a responsive sensation with every step. Enter an unreal experience of movement. Unreal Cushioning Our Dynamic Air system features dual-chambered tubes with tuned pressure levels. This means airflow shifts within each set of tubes in response to compression, providing a custom cushioning experience. Unreal Motion The full-length Dynamic Air system sits directly on top of the rubber outsole to get you as close to the ground as possible for smoother transition. Plush foam is placed underfoot for additional comfort. Unreal Flow Sculpted upper is made of lightweight mesh on top, while slashes at the sides reveal open mesh for more breathability. Design lines help radiate energy throughout your look. Plastic heel clip helps hold your foot down for more containment. Extra layer across toe tip adds durability.
