I only had opportunity to wear these shoes once so far for an 8 hour shift on my feet. My feet did not hurt or burn at all by the end of the night like in my other work shoes. There was plenty of room for the one toe that always rubs on other shoes. If my feet swelled there was plenty of room. They were not tight by the end of the night. I'm not sure if I can run in these due to the loose fit of a clog-like shoe. If anyone has any insight into if I choose a size too large or the right shoe for my job. Sometimes I need to do tasks quickly with short spurts of running. Ouy! I gave it 4 stars since I only wore them once. Stay tuned....that could change up or down.
