Alphafly 4

The Men's Nike Alphafly 4 is Nike’s legendary marathon racer, redesigned to deliver more energy with less weight.

An updated Air Zoom unit provides a softer, quieter feel, while dual ZoomX and ZoomX LT foam delivers a lighter, springier ride with exceptional energy return.

A wide carbon-fiber Flyplate creates a propulsive sensation while maintaining the stability needed to power through 26.2 miles.

Finished with an updated breathable Atomknit upper and midfoot containment cables, the Alphafly 4 is engineered for race-day speed.
