The Air Zoom Alphafly Next%2 are designed for race day and beyond, to help you shave valuable time off your personal bests. Enjoy the best energy return of any Nike running shoe with this updated version of the Alphafly. Zoom Air lateral pods in the forefoot deliver Nike's highest energy return cushioning system, adding more rebound with every step. The outsole along the forefoot has less rubber but improved traction and more ZoomX, a much more capable material right under the balls of your feet as you hit the ground and take off in your next stride. Your feet rest on the full-length ZoomX foam for an ultra-light and responsive ride. It's built for speed but also offers unrivaled cushioning to stay cool even in the final miles of a marathon. It offers protection and comfort where you need it. The full-length carbon fiber flyplate provides a sort of forward-rolling feel that makes you want to take the next step. It gives you a feeling of propulsion and helps you transition smoothly throughout your stride. The forefoot and heel offer slightly wider bases for a stable platform so you can tackle turns on the course with confidence.
