Your happy place: The lower stratosphere. You wanted shoes that would make you feel like walking on air. And Nike delivered. Instead of burying an Air unit inside the sole, Nike has moved its Max Air cushioning directly under your foot, replacing a traditional midsole. The Max Air cushioning is soft underfoot, while the Flyknit plus Flywire upper matches it in off-the-charts comfort. Which probably explains why runners voted it the most comfortable Nike running shoe.
