The toe box on these shoes are outstanding, though for my feet, the width is just a hair shy of comfortable for long term wear. Ironically, the heel of the shoe is somewhat wide and short which leads to some sliding. With a thicker athletic sock, it is a comfortable shoe that rides nicely during a run, and the zero drop is much appreciated. If you were to take the Brooks Pure Flow 2 body and add the Altra toe box, you'd have a winner!
