These look great, however in the medical/dental field I am on my feet and running around a good amount of time throughout my 10+ hour days. These shoes are SO incredibly uncomfortable and do not flex at all, even with trying to break them in prior to use at work! I have BRUISES on top of my feet where these sit!!! They are stubborn as all heck and won't hardly budge or flex when walking. Also, the bottom broke apart by the toe (mind you I wore these LESS than 5 hours). I could get about an hour in these shoes and had to constantly be taking them off throughout the day. They would be quite comfortable if I could just get past how stiff they are. Would not recommend, or if you want to spend forever trying to break these in I would go a size bigger. Save yourself from being in so much pain!<br /><br />Update: I have had these maybe a little over a month and they have hardly broken in. I have tried breaking them in and wearing them around the house before and on my feet over 10 hours a day they're still stiff. I have permanent numbness on the tops of my feet where they lay. They are also cracking on the tops AND the bottoms have fallen apart. Would not recommend, especially in the medical or dental field
