The Dn8 low-top sneakers feature Nike's Dynamic Air system, which is powered by eight pressurized air tubes. The dual-chambered tubes feature tuned pressure levels. Airflow shifts within each set of tubes in response to compression. The Dynamic Air system sits directly on top of the rubber outsole. They also feature a plush foam underfoot. The upper is made of lightweight mesh and an extra layer across the toe tip for durability. A plastic heel clip helps hold your foot in place for more containment. They feature a foam midsole, rubber outsole, and lace up closure.
