The Air Max Dn features our Dynamic Air unit system of dual-pressure tubes, creating a responsive sensation with every step. This results in a futuristic design that's comfortable enough to wear from day to night. Go ahead-feel the unreal. Maxxed Out Motion - Our Dynamic Air unit system features two 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. Maxxed Out Comfort - 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.
