As a career firefighter, I find these to be the best boots I've owned. They are true to size, and easy on and off. They do not feel loose, or tight. They are perfect while on duty over having zipper boots. They can easily be slipped on and off when having to get in and out of turnout gear boots multiple times a shift. No need to bend over and unzip your boots before taking them off, just kick these off and put your turnout gear on. I'm on my forth year in the these boots and am finally looking into replacing them with the same kind, but i'm sure I can get another year out of these.
