While the show is very sturdy and does it's intended job of protecting the feet while working, I find that the shoe makes my feet extremely hot after wearing for about 5 or 6 hours.
There seems to be no way for the foot to "breathe" in these and after a while, it felt like my feet were on fire. They also felt a bit snug up front as my small toe was beginning to hurt after a while...but strangely it only happened on the left foot, while the right was fine.
At the end of the workday, when coming home and removing the shoes, my socks were all sweaty which never happens so I will be returning for a more "breathable" shoe.
