More Air, less bulk. The Dn8 takes our Dynamic Air system and condenses it into a sleek, low-profile package. Powered by eight pressurised 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. Product details: Not intended for use as personal protective equipment (PPE) More benefits: The plastic heel clip helps hold your foot down for more containment. The extra layer across the toe tip adds durability. Max Air unit: Visual stunner. Window to the sole. Legendary designer Tinker Hatfield took cues from inside-out Parisian architecture to re-establish Air technology as a leader in cushioning. Plush and comfortable, the Max Air unit has just the right amount of support.
