The Air Max 720 ‘Obsidian’ brings a subdued look to its bold construction, which boasted the tallest-ever Max Air unit at the time of its release. The shoe’s molded upper is finished in Obsidian, accented by Royal Pulse, Regency Purple and Blue Fury on the supportive overlays and branding. Underfoot, the signature 720 Max Air unit provides cushioning, giving way to a rubber tread for traction.
