It's time to significantly update your personal best. Optimal Energy Return for Marathons The combination of two Air Zoom units in the forefoot and ZoomX foam stores energy. This energy return powers your stride. A Feeling of Being Pushed Forward The full-length carbon fiber plate provides a feeling of being pushed forward. Weight transfer with each stride becomes smoother, allowing you to change direction with confidence. Cushioned Comfort The fully integrated ZoomX foam provides an exceptionally lightweight and cushioned feel. It keeps you fresh and comfortable from start to finish. New Features of the Alphafly 3 The Alphafly 3 is the lightest in the Alphafly series.

Other Features Cut-in laces provide a soft yet secure closure. The integrated knit tongue and thick padding reduce pressure from the laces.
