These are leather, so I expect they will stretch over time! If you have the misfortune of having a bunion, I would suggest a different style if you don't want to break the shoe in.  The first wear out of the box was somewhat uncomfortable but the 2nd try was much better...I'm hoping the 3rd try will be the charm! I likely won't buy these again but I won't return them, either! Using them as they were intended may be your best bet...Cross-Training...but for me, I'll stick to the Nimbus for running!
