LARGE AIR GETS A LIFT. The Air Max 720 20 updates a modern marvel with iridescent materials. Nike´s tallest Air bag provides the most underfoot cushioning for ultimate comfort while iridescent details give your game a lift. Has Air Max gone too far? We hope so. Nike's largest Air unit to date, the 720 Air unit runs the length of the outsole. Molded lines in the upper appear to radiate out from the pods, creating a wavelike design. Iridescent design inspired by the shimmer of bubbles.
