Product Details The Nike Air Max Dn is defined by its innovative Dynamic Air cushioning technology. The set up consists of a dual-chamber, four-tubed Nike Air unit that looks to provide you with unparalleled comfort, a smooth stride, and maximum bounce. Dynamic Air’s design involves higher pressure (15 psi) in the back chamber’s two tubes near the heel and lower pressure (5 psi) in the front two tubes. This results in a seamless heel-to-toe movement, with air flowing freely between the tubes as you move, responding dynamically to your body’s load. Reggie Hunter, Nike’s Product Director for Lifestyle Footwear, explains the concept of "dynamic motion," emphasizing how the independent chambers enable real-time interaction, ensuring the air unit moves seamlessly with each step. This breakthrough was first achieved with the Nike Air Max Dn. Aside from the Dynamic Air unit, the sneaker also features a TPU shank arch clip in the midfoot for structure and support, along with a TPU heel counter that supports the Achilles. The midsole features Injected Phylon foam, while the rubber outsole offers street-ready traction and durability, as it wraps around the heel. The upper features a modern textile build along with a textured overlay with a silicone finish, creating a fluid feeling reminiscent of the smooth heel-to-toe transition.
