Nike Air VaporMax After the 7-year journey from ideation to release, the Air VaporMax represents a new era in Nike innovation. To truly capture the feeling of “running on air,“ the designers restructured the Air unit to be attached directly to the upper. As you step down, each lug gets pushed into the Air unit, ramping up the pressure. Then, as you step off, the pressure releases creating springy bounce with superior flexibility. Made for runners, the futuristic technology was quickly adopted by the street, bringing this light-as-air feeling to the masses.
