The Air Max Dn features a Dynamic Air unit system of dual-pressure tubes, creating a reactive sensation with every step. The Dynamic Air unit system features 2 sets of dual-pressure tubes. With the firmest amount of pressure in the heel and the softest amount of pressure toward your midfoot, the air levels shift within each set for a smooth transition as you step. Multilayered mesh on the upper feels lightweight and breathable, with a haptic print for a textured look. Plush foam surrounds the cushioning system for an enhanced feel that's uniquely soft and supportive. Providing comfort from top to bottom, this tactile design boasts performance-level bounce to energize your every move. The Nike sneakers feature matte accents, a foam midsole, and a rubber outsole. They are not intended for use as Personal Protective Equipment (PPE).
