When I wear my steel-toe boots for a couple of house, there was no problem. But after a few hours that edge on the tor bothered the heck out of me. To the point that I would get blisters. I was ready to blame the boots, but decided to do some research. Ah - special socks. Made sense. I ordered several different pairs.  For all day use, these are the best. The padding on top goes further - past the toes. It's thicker and provides more cushion against that steel edge.  Use steel toe boots or shoes all day? Get these socks!
