These shoes are very comfortable. I work 12 hours a day in steel toe shoes on concrete. My feet hurt horribly. These shoes are a welcome relief. After reading reviews stating that these shoes run small, I ordered a size larger. I also must have wide width shoes, I had no troubles with these shoes. I did not have troubles getting acclimated to these shoes, they feel very natural. Some reviews stated that they experienced some muscle pain while getting used to these shoes, I did not share this experience. I will repeat this order in the future.
