Ok, so this is advertised to be a work shoe for working in food service. Well, I'm a chef, and am on my feet 8 - 14 hours a day in very warm conditions. In a commercial kitchen, it can get ten to twenty degrees hotter than outside. After one day of wearing these, my feet were wrinkled and smelly from being covered in sweat all day. If I actually stood still for more than a minute, I would wonder what it was I was smelling. It turned out that it was my feet. I have never had that happen before.

So, to sum it up: Solid rubber shoes with no ventilation in hot conditions = smelly sweaty disaster. I ended up drilling some holes in the shoes for ventilation, but toes have to be covered by health regulations, so could only do so much. Some odor eaters powder helps, but has to be applied daily, and the white powder shows up on the black very easy.

I had to give it two stars instead of one only because they are very comfortable to stand in all day. My suggestion to the manufacturer: Make some grooves or something to allow a little air to get in, or at least a little space between the sides/top of our feet and the solid rubber.
