Experience a new level of comfort in the Nike Air VaporMax 2021 Flyknit. A stretchy Flyknit upper wraps your foot in flexible, airy support while heel-to-toe VaporMax Air cushioning leaves you feeling like you’re walking on clouds. Stitched-on Swoosh designs and a plastic heel clip add a splash of visual intrigue as you glide down the street. Breathable Support Supportive Flyknit upper is made from stretchy yarns and creates a striking visual that's seamless, breathable and lightweight. It allows for smoother transitions and adds lasting cushioning. Sporty Comfort Collar sculpts the ankle for a sporty look that feels great while padding on heel adds to the comfort. The Grind Speckles in the rubber outsole are made from Nike Grind, which is recycled waste (i.e., the scraps) from the footwear manufacturing process. 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.
