The Alphafly 3 road racing sneakers are designed for marathon runners. These Nike athletic sneakers feature two forefoot Air Zoom units that combine with ZoomX foam to store and return energy. A full-length carbon fiber plate delivers a propulsive sensation, facilitating smooth transitions through every stride. The fully connected ZoomX foam creates a cushioned feel, while the Atomknit upper is designed for improved multidirectional containment and breathability. The notched lace-up closure ensures a secure fit, and the integrated knit tongue with lofted padding alleviates lace pressure. The sneakers have an 8mm heel-to-toe drop and weigh approximately 174g/6.1oz (size US 8).
