I'm not in the USMC or in construction, but I am on my feet a lot n need a sturdy shoe that can take a beating. I've been looking for a good boot for my line of work, but these boots in particular are hardcore. Heavy duty steel toe. Little much. Been used and abused but a great boot. So I'm posting them merely because they surpass what would work for me. Maybe they'd work better for you. Used but in good condition.
