These work boots are just ok. I work 12 hours days. And by the end of the day, my feet are killing me. Through to about midday through my shift Im not doing too bad, but I cant wait to take them off when I get home. I don't think that the memory foam is thick enough. When standing or walking, you can feel your feet sink into the footbed, but then its like you are standing on flat concrete. If the memory foam was thicker, I think that these would be much better and feel better. It just feels like there is no cushion on it at all after you take steps or are standing. I would like to try them again if they are ever reproduced with thicker memory foam. But for now, they were pretty much a bust for me.
