Celebrating Eliud Kipchoge's record-breaking 5K performance in 2003, Nike's Alphafly 2 is adorned with his record time and quotes in the insoles while the red stripe through the Swoosh logo harks back to when the athlete wore Zoom Miler spikes. The fit comes in white tones, with breathable AtomKnit being a lightweight but durable choice for the uppers. Zoom Air units sits below, working in tandem with a full length Zoom X foam midsole to deliver optimal levels of cushioning from forefoot to heel. The fit is also equipped with a carbon fibre unit too, for smooth transitions up and down those trails. To sign things off, a rubber sole underfoot ensures that you tackle uphill terrain with ease. | FD6559-100, Textile & Synthetic Upper/Synthetic Sole.
