    My overall experience has been fairly pleasant. I just wish it was a little bit softer underfoot.

  • 64 / 100 | RIZKNOWS

    Overall, I’m just lukewarm on these shoes. They have some positive attributes going for them but I just wish the heel lock-in was a little better.

  • 90 / 100 | Trail to Peak

    The fit and comfort have made this a shoe I reach for on my shoe rack time and again.
