The Nike Air Max Dn8 sneakers feature a Dynamic Air system powered by eight pressurized Air tubes that offer responsive cushioning. The dual-chambered tubes with tuned pressure levels allow airflow to shift within each set of tubes in response to compression, delivering a custom cushioning experience. The Dynamic Air system spans from heel to toe and sits directly on top of the rubber outsole for smoother transition. The upper is made of lightweight mesh. The plastic heel clip helps secure the foot. A foam midsole and an extra layer across the toe tip add durability. These are athletic sneakers.
