The Air Max Dn sneakers feature a Dynamic Air system with dual-chambered tubes with tuned pressure levels. The airflow shifts within each set of tubes 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. There is plush foam underfoot for additional comfort. The sculpted upper is made of lightweight mesh, while slashes at the sides reveal open mesh for more breathability. The sneakers have a plastic heel clip to help hold the foot down for containment. An extra layer across the toe tip adds durability. They have a foam midsole and a rubber outsole. FQ7860-001.
