When taking turns, the shoe can feel a little unwieldy – that’s why the Vaporfly 2 is the better option for twisty courses, especially over 5K and 10K distance – but once you hit a straight there’s no faster shoe available than the Alphafly 2. When you’re running straight on good roads, the energy return you get from the ZoomX foam and Air Zoom pods underfoot is unrivalled, and the Alphafly 2 makes ticking off kilometres at race pace feel almost effortless at times.

While these changes make the Alphafly 2 heavier than its predecessor, the result is an even more impressive shoe that we rate as the best marathon racing shoe on the market. The second edition of Nike’s top carbon racer has some small but important updates on the original: more foam under the forefoot, more structure in the upper, and a refined geometry to make the transition from heel to toe smoother.
