The Dn8 sneakers feature a Dynamic Air system powered by eight pressurized Air tubes for a responsive sensation with each step. The dual-chambered tubes with tuned pressure levels allow airflow to shift in response to compression, providing a custom cushioned experience. The Dynamic Air system spans from heel to toe and sits directly on top of the rubber outsole for smoother transition, while plush 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 plastic heel clip helps hold the foot down for more containment. The extra layer across the toe tip adds durability. The midsole is made of foam. These are athletic sneakers by Nike.
