Nike Alphafly 3 Hyper Pink Crimson Tint Carbon Racer

Some colorways become instantly familiar in race photos, and Hyper Pink / Crimson Tint is one of them. The pink Atomknit upper melts into a softer crimson midsole for a tonal warm gradient rather than a hard contrast.

The shoe behind a record

Kelvin Kiptum wore the Alphafly 3 to the men's marathon world record. It is lighter and smoother than the Alphafly 2, with three systems returning energy on every stride, making it a natural pick for the race you have trained all year for.

• Full-length ZoomX in a single molded piece
• Carbon-fibre Flyplate heel to toe
• Two forefoot Air Zoom pods for a springy push-off
• Atomknit 3.0 upper that is thin, breathable and water-resistant
• 8 mm drop; roughly 201 g in a men's US 9
