I'm in the military and will NEVER take comfortable footwear for granted. I wear the same boots all day long, Altama 8" EXOSpeed's (Desert). I switch from my new one's to my two-yr old one's as soon as I switch jobs. They aren't steel toes, but they are extremely well-made and are, by far, the lightest boots I've ever had! To me, they feel like tennis shoes compared to what I had always worn before. Their site has some big discounts that are far cheaper than buying full price around military installations.
