Our Verdict
Nike Pegasus 41
Nike Structure 26
The Nike Pegasus 41 and Nike Structure 26 are contemporary iterations of two of the swoosh's most long-running shoe series. Both have undergone numerous updates over the decades without changing their respective identities: the Pegasus a daily workhorse, and the Structure a dedicated stability trainer. Neither is built for speed, but rather for reliably plodding through miles upon miles. For runners with a neutral stride, looking for a no-fuss trainer that can endure the daily grind, the Pegasus 41 is a solid option. For runners whose form breaks down easily or who have known pronation issues, the Structure 26 is a safe choice.
