Good so far.
Still breaking them in but seem like very nice boots. No long term or hard use of them yet. I like the big toe box. And the composite toe does not make the boot look too bulky. One handy feature that is missing though, is the pull loop on the back to help putting the boots on. But possibly they were omitted because the boots are sometimes worn by EMS personnel, which for safety reasons may not be allowed. I would have preferred that the Carhartt name didn’t appear on the side of the sole.

Worth the money!
I got these boots last year as a birthday gift from my Wife and daughter. They fit great then, solid lacing, supportive and comfortable. Waterproof is definitely strong and reliable. I'm sure I've walked well over 1,200 miles in these boots and the tread is finally showing it's age, but the rest of the boot is going strong. I work in a shop setting and these are by far the best work boots I've owned!

Comfort, quality and worth every penny
The most comfortable work boots I've purchased yet. I was skeptic at first because I have not worn steel or composite toe sime my military days, 1996. No breaking in needed, after the first 10 hours on the job, these boots are quite comfy. I highly recommend!

Beta boots I even bought.
I've had these boots for about 5-6 years. Wore them for the first 3 years almost every day. They were amazing friends t after brake in, and very comfortable. I work as a mechanic and they did everything needed of them. I again the last year work in them every day and the only downfall after 5 years is where the upper collar meets the leather the stitching broke. And the sole cracked width wise down the center. I loved them a lot and am buying a new pair. And when they wear out will get another. I'm a carhartt for life work boot person. May I say I love there work pants as wel are very good fit and lasted just as long.

Great Boots
I've been wearing these for a couple months now. Great fit. Great feel. Great durability. Handsome. I love wearing them. In fact I love them so well that I want a second pair. I wish all my foot wear were of similar quality. Sadly most of my foot wear is no where near the same quality. I recommend these boots.

This is the most comfortable steel toe work boot I have worn. The quality is still holding up after a year of 12 hour shifts on a concrete floor. I highly recommend this boot.

Nice looking boot that shows promise
My wife bought these for my birthday today(Sept 8) and I enjoy the room and feel of the boot on my feet. I have yet to really wear them at work yet, but I will reshare in a few months.

Best snow boots
I hadn't had much luck with boots keeping my feet dry during winter until I happened upon Carhartt's 6-Inch Rugged Flex Black Boot. Slush is a huge problem here in NYC; crossing the street can be an ordeal, but not with these boots The tread prevents me from slipping and the boots provide ample ankle coverage and water-proofing to keep my socks dry. Highly recommended - terrific value.
