The Next Generation of Fast
When Eliud Kipchoge ran a marathon in 1:59:40 in 2019, he did so in a prototype of the Nike Air Zoom Alphafly NEXT%. For over two years we collaborated with Kipchoge to develop a shoe designed to help every athlete reach their goals. The result is the fastest racing shoe we've ever made.
Carbon-Fibre Plate Proportioned to the Size of the Shoe
Working in tandem with the ZoomX foam and the Air Zoom pods, is a full-length carbon-fibre plate that delivers a snappy sensation with each stride. For the Alphafly NEXT%, the thickness was 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.
Introducing AtomKnit
During testing, the Nike Innovation team discovered that with the additional foam and the two Zoom Air bags underfoot, the overall weight of this shoe increased. To shave off some grams, the Nike Innovation team developed a new Flyknit upper called AtomKnit. Flyknit fabric is steamed and stretched, delivering a lightweight, contoured fit with minimal water absorption and enhanced breathability.
