The Finer Details Two forefoot Air Zoom units combine with ZoomX foam to store and return the energy back to you, powering every step. A full-length carbon fiber plate delivers a propulsive sensation that helps you smoothly transition through every stride and tackle turns with confidence. Fully connected ZoomX foam creates an ultralight and cushioned feel, helping you stay fresh and comfortable from mile 1 to 26.2. The Alphafly 3 is Nike's lightest Alphafly ever, featuring a slightly wider carbon fiber plate for increased stability, a fully connected ZoomX foam midsole for smoother transitions and an all-new Atomknit upper designed for improved multidirectional containment and breathability. Notched laces offer a secure but soft lace-up. Integrated knit tongue with lofted padding helps alleviate lace pressure. Nike Mens Alphafly 3
