It has a new sandwich mesh, a new midfoot webbing system and a longer, more padded tongue. The Pegasus 38’s new upper is wider in the forefoot and built on the same last as previous versions of the Pegasus, before the 37th version. The Pegasus 37 felt like a rough prototype that should never have seen the light of day and most of the problems were upper related. When a shoe has been around for 37 years, everyone expects it to be perfect but the Pegasus 37 was far from it. These flaws were very uncharacteristic for the always consistent, ever-reliable Air Zoom Pegasus.

Its narrow fitting upper caused runners to get blisters on the medial side for their feet while the heel cup was too shallow so it resulted in major heel slippage. Most of the running shoes mentioned above didn’t really need an upper update but the Pegasus 37 was in dire need of one. The year of 2021 is turning out to be a year of minor changes for Nike with the Pegasus 38, Vaporfly Next% 2, Miler 2 and Infinity Run 2 all receiving upper-only updates.
