The Air Max 720 silhouette has a new 720 Max unit, and this number is derived for its 360-degree coverage in the vertical range, while the eccentric upper is designed with retro-futuristic aesthetics in mind. The marquee feature of this shoe is its extra-large Max Air unit, which is made with 75% recyclable manufacturing waste and is 6 mm taller than the 32 mm unit on the Air Max 270. The iridescent midsole is complemented by a synthetic mesh upper with a unique purple hue. The mesh upper of the Nike Air Max 720 Northern Lights Night Sneakers has metal details wrapping around the shoe. The transparent full-length Max Air sole unit completes the design.
