Nike Alphafly 3 Men's Road Running Shoe for Competition The Alphafly 3 is designed to match the speed of a marathon and help you push your limits – and overcome them. Three innovative technologies drive your run: a double dose of Air Zoom units help you take the next step, a full-length carbon fibre plate ensures you progress with ease, and a ZoomX foam midsole from heel to toe keeps you fresh from start to finish. It's time to leave your old personal records behind: run away yourself. Energy for your marathon Two Air Zoom units in the forefoot, combined with ZoomX foam, store and release the energy for more power with every step. Driving feel A full-length carbon fibre plate provides the right push forward, helping you roll smoothly with every step and master curves confidently. Cushioned Running The fully bonded ZoomX foam provides an ultra-light, cushioned feel that provides freshness and comfort from mile 1 to 42. What's new on Alphafly 3? The Alphafly 3 is the lightest Alphafly ever. It features a slightly wider carbon fibre plate for added stability and a fully bonded ZoomX foam midsole for softer transitions. Also included is a completely new Atomknit upper for improved multi-directional cushioning and breathability. The textured laces provide reliable yet gentle grip. An integrated knitted tab with soft padding provides reduced pressure from the laces. Weight: 218 g (men's shoe size 43) Drop: 8 mm
