Nike Air Zoom Alphafly Next% 3 Marathon Super Shoe. The lightest and most tested

Nike Air Zoom Alphafly Next% 3 Marathon Super Shoe. The lightest and most tested Nike Alphafly ever, tested and validated by elite marathon runners and featuring Air Zoom cushioning, designed to help runners achieve breakthroughs and better results. During its development, 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, retaining the Air Zoom cushioning unit, Flyplate carbon fiber plate, and Zoomx foam. However, the overall system's construction method has been slightly adjusted, optimized, and improved to enhance its support for athletes. Key updates include a one-piece sole providing a smooth and stable "heel-to-toe" transition; a wider full-length Flyplate carbon fiber plate providing stable propulsion; a new Fast Shot outsole ensuring excellent traction and grip; and a new Atomknit 3.0 upper providing enhanced control, breathability, and midfoot support.
