The 40th revision of Nike's Pegasus is the most popular shoe on LetsRun.com and also the most divisive one. Over a third of reviewers give it a perfect overall score, but over 20% give it failing or near-failing marks. Those who like it praise its comfort, fit, and performance on runs and workouts. Those who dislike it complain that the fit has changed enough from previous revisions that they cannot run in the shoe any longer.
