Nike Alphafly 3 Sail Crimson Tint Guava Ice

Built for: Marathon race day and your fastest tempo sessions.

The Alphafly 3 is Nike's flagship marathon racer, rebuilt around a single full-length ZoomX midsole, a carbon Flyplate and two Air Zoom pods under the forefoot. Lighter and smoother than the Alphafly 2, and the shoe Kelvin Kiptum wore to the men's marathon world record in Chicago.

Why it works

• Full-length ZoomX midsole — Nike's lightest and most responsive foam, now molded as one piece for a smoother transition.
• Carbon-fibre Flyplate runs the length of the shoe, stiffening toe-off and driving you forward.
• Two Air Zoom units under the forefoot load on landing and release at push-off.
• Atomknit 3.0 upper: thin, breathable and water-resistant, holding the foot at speed without adding weight.

Race-day details

• Surface: Road, race courses
• Best for: Marathon, half marathon, race day and fast tempo
• Drop: 8 mm
• Weight: ~7.1 oz / 201 g (men's US 9)
• Ride: Aggressive and propulsive — built for pace, not for easy miles

Sail / Crimson Tint / Guava Ice

A warm, softly tonal make-up: Sail across the Atomknit upper with Crimson Tint and Guava Ice through the midsole and branding. Quieter than most Alphafly colorways without losing the shoe's shape.
