The Dn8 sneakers feature a Dynamic Air system powered by eight pressurized Air tubes, mesh upper, and rubber outsole. The dual-chambered tubes with tuned pressure levels allow airflow shifts within each set of tubes in response to compression, providing a custom cushioned experience. Spanning from heel to toe, the Dynamic Air system sits directly on top of the rubber outsole to get you as close to the ground as possible for smoother transition. Plus foam is placed underfoot for additional comfort. The sculpted upper is made of lightweight mesh on top, while slashes at the sides reveal open mesh for more breathability. The Nike sneakers also features a plastic heel clip and an extra layer across the toe tip for durability.
