The Alphafly 3 is our lightest Alphafly ever, featuring a slightly wider carbon-fibre plate for increased stability, a fully connected ZoomX foam midsole for smoother transitions and a Flyknit upper designed for improved multi-directional containment and breathability. Integrated knit tongue with lofted padding helps alleviate lace pressure. Nike is doing much better than the Vaporfly 3 , which was a flop and far below the level expected of it. Targeting a wider audience with greater comfort and stability, we're sure to see plenty of Alphafly 3s at the start of races, mainly semis and marathons.

Speed for all We rigorously tested the Alphafly 3 in the Nike Sport Research Lab, gaining insights from the largest ever women's testing pool for a Nike racing shoe. The feedback from both elite and everyday runners ultimately improved the comfort of the Alphafly for all marathoners, from a widened footbed and fully connected outsole that enables a better fit and natural heel-to-toe transitions to softer yarns in the upper for less rigidity and rubbing.
