Model Number: CI9925-300 Best use Best Use Learn More If you're looking for the latest and greatest technologies to take your performance to the next level, add the Nike Zoom Alphafly Next% to your collection. These three critical components are complemented by the latest evolution of the Flyknit upper, called AtomKnit, which is steamed and stretched to deliver a lightweight, contoured fit with minimal water absorption and enhanced breathability. Additionally, the ZoomX midsole is not only taller but wider which means you gain added protection and cushion with a more stable ride. Unlike the Vaporfly where a single thickness of carbon fiber was used for all sizes, the Alphafly's carbon fiber plate is scaled for the size of each shoe-the plate is more flexible in smaller sizes and gets stiffer as the size of the shoe increases. Thanks to dual, visible Zoom Air units in the forefoot, a full-length carbon fiber plate, and a higher volume ZoomX midsole, the Alphafly Next% is able to store and return even more of your energy while providing added cushioning.

Designed to complement rather than replace the Vaporfly, the Alphafly Next% provides runners with more energy return, impact protection, and cushion at a slightly heavier weight. Worn by Eliud Kipchoge when he ran 26.2 miles in 1:59:40, the Nike Zoom Alphafly Next% is the first running shoe to break 2 hours in the marathon.
