Nike Alphafly 3

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.
