This is my third pair of Caterpillar work boots and the most comfortable yet. I work in a printing company so I'm on my feet on a cement floor all day and jumping on and off of a metal catwalk as well. I never cared for work boots in the past. The cheap $30-$40 boots from Walmart and KMart are a waste of time. These are AWESOME. All day comfort, no sweaty socks, no steel shank digging into the tops of my feet. They hit a homerun with the Second Shift boot. I'll never buy anything else.
