variable density walls balance lightweight feel with structural integrity

Fine-tuned for marathon speed, the Alphafly 3 helps push you beyond what you thought possible. Three innovative technologies power your run: a double dose of Air Zoom units helps launch you into your next step; a full-length carbon-fibre plate helps propel you forwards with ease; and a heel-to-toe ZoomX foam midsole helps keep you fresh from start to 26.2. Time to leave your old personal records in the dust.

Energy return for your marathon - Two forefoot Air Zoom units combine with ZoomX foam to store and return the energy back to you, powering every step.

Propulsive feeling - A full-length carbon-fibre plate delivers a propulsive sensation that helps you smoothly transition through every stride and tackle turns with confidence.

Cushioned ride - Fully connected ZoomX foam creates an ultralight and cushioned feel, helping you stay fresh and comfortable from mile 1 to 26.2.
