Company Level! Nike Air Zoom Alphafly Next 4, the all-new marathon ultrarunning

Company Level! Nike Air Zoom Alphafly Next 4, the all-new marathon ultrarunning shoe, is the lightest and most tested NK Alphafly ever. Proven by elite marathon athletes and equipped with Air Zoom cushioning, it's designed to help runners achieve breakthroughs and better times. During development, the Alphafly 3 helped Nike athlete Kelvin Kiptum break the marathon world record with a time of 0:35. The Alphafly's dynamic design remains unchanged: the Air Zoom cushioning unit, Flyplate carbon fiber plate, and Zoomx foam, but the overall system's construction has been slightly tweaked to optimize and enhance athlete support. Key updates include a one-piece sole that provides a smooth and stable heel-to-toe transition; a wider, full-length Flyplate carbon fiber plate for stability and propulsion; a new Fast Shot outsole for exceptional traction and grip; and a new Atomknit 3.0 upper for enhanced control, breathability, and midfoot support.
