Nike Air Zoom Alphafly Next% 4Proto

Product Description

The Nike Air Zoom Alphafly Next% 4 Proto introduces updated cushioning and a lighter construction to Nike’s marathon racing lineup. The Proto edition pairs a Sea Glass, Laser Crimson, Phantom, and Burgundy Ash palette with a sculpted platform built for road racing. Its exposed Air Zoom cushioning and curved forefoot give the shoe a recognizable technical profile, while the knit upper keeps the construction visually light.

The fourth-generation design combines ZoomX foam with ZoomX LT, Nike’s lighter cushioning formulation, alongside an updated Air Zoom unit engineered for a softer, quieter feel. A wide carbon-fiber Flyplate adds stiffness and supports forward transitions. Above the platform, Atomknit incorporates open-mesh zones for ventilation and midfoot cables for containment. Nike lists an approximate weight of 188 grams in a men’s US 8.5 and an 8mm heel-to-toe drop.

This edition marks another stage in the Alphafly’s development, with changes concentrated in the foam, Air unit, and upper. The Nike Air Zoom Alphafly Next% 4 Proto has a scheduled release date of October 29, 2026, and a retail price of $280.
