Nike Alphafly 3 - Elite marathon racing engineered for record-breaking speed

The Nike Alphafly 3 represents the pinnacle of marathon racing technology, refined to help you chase times you once thought impossible. Featuring dual forefoot Air Zoom units, a full-length carbon fiber plate, and fully connected ZoomX foam from heel to toe, this elite racing shoe combines three powerful technologies to propel you through 26.2 miles faster than ever before—now in Nike's lightest Alphafly iteration yet.

Two forefoot Air Zoom units work in tandem with ZoomX foam to create a dynamic energy return system—storing impact force and releasing it back through each stride. This dual Air system combined with Nike's most responsive foam delivers the propulsive power needed to maintain race pace when legs begin fatiguing in the latter stages of marathons. The fully connected ZoomX midsole creates an ultralight, cushioned sensation that protects your legs whilst keeping the ride lively from start line through the final sprint.
