The Nike Alphafly 3 is a high-performance marathon racing shoe, designed to enhance speed and efficiency for long-distance runners. It features three key innovations:

1. ZoomX Foam: The full-length ZoomX foam midsole provides lightweight cushioning and energy return, helping runners maintain momentum throughout a race.

2. Dual Air Zoom Units: Positioned in the forefoot, these help propel you forward with each step, offering additional bounce and responsiveness.

3. Carbon Fiber Plate: This full-length plate enhances stability and propels you forward, making transitions from heel to toe smoother and more efficient.

Other updates include a new continuous sole for seamless heel-to-toe transitions and an Atomknit 3.0 upper for improved breathability and support. The shoe is designed for fast runners aiming for personal bests, but may not be ideal for those running marathons
