Once you take a few strides in the Nike Alphafly 2, you’ll never look at your favorite pair of old racing shoes the same. These rocket ships are made to help shave precious time off your personal records without surrendering the foundation you need to go the full distance. A thick, lightweight support system brings comfort and speed together so you can enjoy our greatest energy return yet while you chase your personal bests.

MAY THE MILES FLY BY

In anticipation of one of the biggest running races, we're celebrating the 20th anniversary of the Nike Mayfly, a popular ultra-lightweight racing shoe. Modernized graphics nod to the original Mayfly while bold race-day colors and Ekiden-inspired details celebrate the sport you love.

BOUNCE TO THE BEAT

Zoom Air units and full-length ZoomX foam bring you our highest energy return cushioning system yet, adding more bounce to every step. A thin rubber outsole enhances traction and allows for more ZoomX foam to be placed under the Zoom Air cushioning. The additional foam not only adds more bounce, but also helps improve transition from heel to forefoot.

STAY FRESHER, LONGER

Full-length ZoomX foam offers an ultra- lightweight and responsive ride. It’s built for speed but also provides cushioning to help you stay fresh even in the last miles of a marathon. It offers comfort where you need it.
