The Nike Zoom Fly Flyknit was specially engineered to meet the demands of world marathoners in 2017. Reintroduced in January 2019, this upgraded 'Deep Royal' sneaker joins the genealogy with a well-ventilated upper defined by fusible yarns that create supportive, structured zones where it counts. Past meets present with an extended carbon fiber plate borrowed from the VaporFly 4% and the addition of React technology and traction diversity.
