Nike Alphafly 4

The Marathon Shoe Finds a New Balance

Nike's Alphafly 4 is the race-day option for runners who want top-end speed without moving to the more radical Apex. It keeps the familiar twin Air Zoom units under the forefoot, but rebuilds the shoe around a new foam package and a more accommodating upper.

Two ZoomX Foams Around One Plate

The full-length carbon Flyplate sits between standard ZoomX and the newer ZoomX LT foam. That layered setup is designed to combine softness, rebound, and the stable rolling motion marathoners need after the early miles stop feeling easy.

Atomknit Returns With a Fresh Fit

A new Atomknit upper holds the foot with a light, breathable structure, while Nike's Fast Shot outsole handles road contact. The changes aim to make the shoe feel efficient over 26.2 miles rather than chasing a narrow, stripped-down sensation that only works for a small group of runners.

Built for the Long Race

Within Nike's System of Speed, Alphafly 4 is the marathon specialist that sits between the accessible Swooshfly and the uncompromising Apex. It arrives in October at $280, giving experienced racers a familiar two-pod platform with a thoroughly revised ride.
