The Nike Air Zoom Alphafly Next% 2 is a high-performance carbon-plated racing flat engineered for elite marathoners and serious runners seeking maximum speed and energy return. Featuring a full-length ZoomX foam midsole with dual Air Zoom units (forefoot and heel) and a carbon fiber plate, it delivers exceptional propulsion and cushioning. The upper uses Atomknit 2.0 fabric—lightweight, breathable, and adaptive—with strategic mesh zones for ventilation and reinforced overlays for lockdown. A distinctive white Swoosh with textured knit detailing contrasts against the black engineered mesh base, while the green-tinted visible Air unit adds subtle visual flair. The shoe sits atop a durable rubber outsole with strategic traction patterns for road grip. Ideal for race day or tempo runs, its aggressive geometry and responsive ride make it one of Nike’s most advanced marathon shoes to date. Perfect for competitive runners prioritizing speed, efficiency, and cutting-edge tech—though its firm, race-oriented feel may require adaptation for daily training. Size range: 39–46.5 (as indicated by HL131300318).
