Mens Nike Alphafly 4

Refining every detail of the shoe, the Nike Alphafly 4 elevates Nike’s legendary racing silhouette to deliver the lightest, most responsive and a more confident ride over the marathon distance. 

Featuring a breakthrough dual-foam setup combining classic ZoomX with ultra-light ZoomX LT, alongside upgraded, quieter Air Zoom units, it unlocks next-level energy return across 42km.

Built with a wider carbon-fiber Flyplate platform and an accommodating Atomknit upper, the Alphafly 4 offers greater stability and forgiveness, making marathon speed more accessible from elite marathoners to everyday runners. 

What to love: 

• 10% more energy return and 5% lighter than its predecessor.
• Every components has been refined to create a smoother, faster and more reliable experience over the marathon distance. 

UPPER

• Reworked Atomknit Upper: Strategic open-hole mesh zones for high-output breathability and integrated midfoot cables for precise lateral containment.
• Wider Forefoot & Heel Collar: Re-engineered shape resolves cramped forefoot fit issues while the updated heel collar locks the rearfoot down comfortably.

MIDSOLE 

• Dual ZoomX & ZoomX LT Matrix: Bottom layer of standard high-rebound ZoomX topped with new ZoomX LT—a compound up to 17% lighter with 8%–10% higher energy return for a deeper, softer sink-in before explosive toe-off.
• Redesigned Air Zoom Units:  Deliver a softer underfoot feel, greater power return, and a noticeably quieter, smoother stride.
• Wider Carbon-Fibre Flyplate: Widened platform and base geometry to stabilise footstrikes as fatigue sets in, while retain its signature propulsive and smooth-rolling feel.
• Enhanced Forefoot Protection: Increased underfoot cushioning through the curved forefoot shields muscles from harsh road impact.

OUTSOLE

• Lightweight Fast Shot Outsole: Ensures optimal traction and grip, helping runners stay connected to the road with every stride.
