Nike Alphafly 3 Bright Crimson FD8315-600

Fire on Top. Ice Underneath.

The Nike Alphafly 3 in Bright Crimson / Lime Blast is the most visually explosive colorway in the Alphafly lineup — a full-red racing shoe that erupts from a mint-green midsole in a collision of opposites. This is what speed looks like when it’s on fire.

• Bright Crimson Atomknit 3.0 upper — Nike’s most advanced racing knit in an intense, saturated fire-red that covers the entire upper from toe to collar in a single burning tone — featherlight, precision sock-like fit with zero energy wasted and maximum presence on the race course
• Gold / Solar Swoosh — a vivid amber-yellow Swoosh that transitions from deep gold at the base to bright solar yellow at the tip, sweeping across the crimson upper in a superheated streak that references the energy transfer happening beneath your feet with every stride
• Lime Blast heel pull tab — a sharp neon green accent at the back that delivers the first hint of the shocking color contrast waiting in the midsole, and makes entry effortless after intense warm-ups
• "NIKE ROAD RACING AF 2025-03" certification badge on the lateral midsole — the official race-day certification stamp that confirms the engineering pedigree beneath the striking colorway
• Mint / Barely Volt ZoomX foam midsole — an ice-cool, pale mint-green midsole that sits in maximum contrast to the blazing red upper — Nike’s most energy-returning compound in a tone so cold it almost glows, creating a fire-and-ice dynamic that makes this shoe unmistakable from any distance
• Lime Blast / Neon Green forefoot Air Zoom pod — a vivid neon-green Air unit glowing at the front of the pale mint midsole, delivering targeted explosive cushioning at the critical point of toe-off and lighting up the bottom of every stride
• Full-length carbon fiber plate embedded in the ZoomX stack for elite propulsive energy return at marathon race pace

Red above. Green below. Nothing in between but carbon fiber and ambition. The Nike Alphafly 3 Bright Crimson / Lime Blast is for athletes who want to be seen from the front — because they’re always at the front.
