This is the shoe Nike built for the days that count. The Alphafly 3 is the flagship marathon racer, the one that's carried world records and chased PBs across every distance. Version 3 is the fastest, most complete one yet.
It's a stack of Nike's best tech working as one. Dual Air Zoom units sit under the forefoot for an explosive, spring-loaded pop, a full-length carbon-fibre Flyplate drives you forward and an ultralight ZoomX foam midsole soaks up the impact and hands the energy back. The result is a ride that stays fast and smooth from the start line deep into the final kilometres. At a 40mm stack it sits right at the World Athletics limit, so it's race-day legal when it matters.
The updated Atomknit upper is light, breathable and locks the foot down, while a redesigned outsole grips in every direction for confidence at speed.
