It’s All About Air
Two streamlined Zoom Air pods in the forefoot deliver even more energy return than just the ZoomX foam that is in the Vaporfly NEXT%.
More ZoomX Foam
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.
During testing, the Nike Innovation team discovered that with the additional foam and the two Zoom Air pods underfoot, the overall weight of this shoe increased. To shave off some ounces, 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.
