Nike Alphafly 4 Running Shoes - More Energy, Less Weight for Marathon Racing

Our legendary racer is back and lighter than ever. The Alphafly 4 updates the Air Zoom unit for the first time in the shoe's history, softer, quieter, and delivering more energy return. Dual ZoomX cushioning with new ZoomX LT foam, wide carbon-fibre Flyplate, and advanced Atomknit upper with open-hole mesh zones. Your marathon potential, unlocked.

Updated Air Zoom Unit — Softer, Quieter, More Energy

For the first time in the Alphafly's history, the Air Zoom unit has been updated. Softer and quieter than previous models whilst delivering more energy return underfoot — don't let them hear you coming. Added cushioning under the curved forefoot enhances protection and propulsion through the full 26.2 miles.

Dual ZoomX Cushioning with ZoomX LT Foam

Two types of foam work together for a lighter, springier ride with smoother transitions. ZoomX foam provides Nike's highest energy return and sits under ZoomX LT foam, the lightest version of Nike's most responsive cushioning. The result is more bounce with less weight, opening up marathon potential without the heaviness that compromises late-race performance.

Wide Carbon-Fibre Flyplate for Stable Propulsion

A wide carbon-fibre Flyplate unlocks a propulsive sensation whilst maintaining the stability needed to power through all 26.2 miles. Width is the key detail , broader than standard carbon plates for a more stable propulsive platform across the full marathon distance.

Advanced Atomknit Upper

Updated Atomknit upper features zones of open-hole mesh for enhanced breathability and midfoot cables for improved containment. Keeps you cool and locked in across marathon efforts where upper performance directly affects focus and comfort.
