I always get nervous when the next generation of a running shoe is released. Will the best parts persist? Or will it be “revolutionary” in a bad way, changing the feel or comfort during a run? In the case of the Pegasus 39, I’m happy to report the shoe is still as comfortable as the 38s, if not more so, while offering fresh color ways. I have three 38s in my rotation, and these 39s fit in nicely. If you’re a fan of the previous gen Pegasus 38, you’ll be pleased with the new Pegasus 39, too.
