Mens Nike Alphafly 4

Lighter, more responsive and more stable than its predecessor, the Men's Nike Alphafly 4 is Nike's most advanced road racer yet, engineered to help runners carry speed efficiently from the opening kilometres through to the finish.

For the first time in Alphafly history, the Air Zoom system has been redesigned to deliver a softer, quieter feel with increased energy return. Dual-layer cushioning combines highly responsive ZoomX foam with new ZoomX LT, Nike's lightest responsive foam, creating a springier ride with smoother transitions and less overall weight.

A wider carbon-fibre Flyplate provides the stiffness and propulsion needed at race pace while creating a more stable platform for maintaining form over longer distances. Additional cushioning beneath the curved forefoot further smooths the transition into toe-off, helping the Alphafly feel controlled as fatigue builds.

An updated Atomknit upper uses open-hole mesh zones to enhance breathability, while integrated midfoot cables improve containment and lockdown. At approximately 188g with a 39mm heel stack and 8mm drop, the Alphafly 4 is designed for runners chasing their fastest performances across half-marathons and marathons.
