Fine-tuned for marathon speed, the Alphafly 3 Premium powers your run with three innovative technologies. A double dose of Air Zoom units, a full-length carbon-fibre plate and a heel-to-toe ZoomX foam midsole help propel you forward as you conquer your next race. Energy return Two forefoot Air Zoom units are combined with ZoomX foam to store and return the energy back to you, powering every step with smoother transitions. Fire underfoot A full-length carbon-fibre plate delivers a propulsive sensation and increased stability that helps you smoothly transition through every stride and tackle turns with confidence. Secure fit Notched laces offer a secure but soft lace-up. The integrated knit tongue with lofted padding helps alleviate lace pressure. What's new about the Alphafly 3? Our lightest Alphafly ever features a slightly wider carbon-fibre plate, a fully connected ZoomX foam midsole and an all-new AtomKnit upper to improve multi-directional containment and breathability.
