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%. This extraordinary achievement was years in the making, the culmination of a collaboration between Eliud and Nike, beginning with Eliud’s effort to break the two-hour marathon barrier in 2017. Eliud’s feat has inspired some of the world’s fastest runners to test their own limits and break their own records, and now the shoe that he wore on that chilly October morning in Vienna is available to us.
Nike's premiere racing shoe is loaded with new technology and innovation that includes two ultra-responsive Air Zoom pods in the forefoot and additional ZoomX foam in the heel. It’s a racing shoe made to shatter records and PRs, whether you’re looking to finish a marathon in two, three, four, or five hours.
Two streamlined Zoom Air pods in the forefoot deliver even more energy return than just the ZoomX foam that is in the Vaporfly NEXT%.
ZoomX foam is unique in two ways: It’s incredibly responsive and lightweight. The Alphafly NEXT% has more foam than the Vaporfly NEXT%, providing additional impact protection and cushion.
Nike scaled the plate thickness for the size of each shoe—it is more flexible in smaller sizes and gets stiffer as the size of the shoe increases, which means that every runner has the same propulsive sensation no matter their size.
