Men's Nike Air Zoom Alphafly Next% 4

The Nike Alphafly 4 is Nike's pinnacle marathon racing shoe, combining a new foam, carbon-fiber Flyplate, and dual Air Zoom units designed to shatter personal bests

For runners looking to bring a high-performance edge to marathon day, the Nike Alphafly 4 combines responsive cushioning, a carbon fiber plate, and Air Zoom units to help you maintain momentum over the long haul.

Nike reworked the shoe's cushioning, plate, and upper to create a smoother experience while keeping the responsive, propulsive character the Alphafly is known for.

The biggest update is the introduction of ZoomX LT foam, a new foam developed for the Alphafly 4. It is lighter than the standard ZoomX and meant to provide a softer, more energetic feel underfoot.

The Alphafly 4 continues to use two forefoot Air Zoom units, with each unit divided into separate chambers. The two units work together under the forefoot to contribute to the shoe's propulsive feel while the updated construction uses less plastic to reduce weight.

A wider carbon fiber Flyplate works with the cushioning system to create a smoother transition through each stride. Combined with additional foam above the plate, the Alphafly 4 has a softer, more cushioned feel while maintaining the rolling sensation expected from a high-level marathon racer.

The new Atomknit upper provides a lightweight, secure fit with improved breathability, including a more breathable toe box for added comfort during long-distance efforts. Underneath, the lightweight Fast Shot outsole provides traction for road racing without adding unnecessary weight.

As Nike's pinnacle marathon racing shoe, the Alphafly 4 combines lightweight cushioning, Air Zoom units, and a carbon fiber Flyplate to deliver a smooth, propulsive ride.
