Running PerformanceĪs someone who liked the Pegasus 37 and 38 as comfortable easy-run shoes, my main worry for the 39 was that the changes would make it feel less cushioned, and so I made my first run in the shoe an easy one. I have also tested the past five versions of the Pegasus extensively – here’s all our Nike Pegasus coverage if you want to dive down memory lane. I have run just shy of 50km in the Pegasus 39, using it for a range of runs from a short, sharp track session up to a 22km long run.

That weight loss has also been achieved without reducing the rubber coverage on the shoe’s outsole, which is good because it’s one of the Pegasus 38’s strong points. These changes to the upper and midsole have seen the Pegasus drop from 310g for the Pegasus 38 to 279g for the 39 (in my UK 9), a substantial and welcome weight loss. This has been added to increase the responsiveness of the ride. The midsole remains primarily made of Nike’s React foam, but where the Pegasus had one Air Zoom unit encased in the foam under the forefoot, the 39 has two, with the second pod found under the heel. I found that the fit was the same as on the 38, and was happy in my normal running shoe size.

This is still a shoe designed for comfort as much as anything else, but overall the upper is less noticeable when you run in the Pegasus 39, which is a good thing. There is still a generous amount of padding on the tongue and around the heel.
