Nike's largest Air unit to date, the 720 Air unit runs the length of the outsole. Colors take inspiration from the natural world, a counterpoint to the shoe's futuristic look. Mesh pods on the lateral and medial sides provide midfoot structure and stability. Molded lines in the upper appear to radiate out from the lateral and medial pods, creating a wavelike design. Waffle-inspired rubber coverage on the outsole for durable traction. Clear rubber on the heel highlights the Max Air unit.
