I’ve been a Heavy diesel mechanic working at a truck dealership and I’ve gone thru boots as quick as 3 months. The first things to go on normal boots are the toe, lace clips, and the heel. The Perkins have designed all of those issues out. The toes have composite safety toe to reduce weight, and boast a rubber toe cover to prevent premature wear. The heels are also extra thick with padding to keep me comfortable through the day. The lace clips are super heavy duty and have held up great. I waited a couple of months after ordering to review to insure I got the right stuff and I did. This is the last pair of boots I’ll ever buy. Not only are they tough. They are the most comfortable pair of boots I’ve ever put on. Never had so much support in my feet. I was hesitant about ordering boots online but I was wrong. Best purchase ever.
