Good for summer not winter
Great boot for summer, very comfortable boot. The toe area is good if you have wider feet. Once it starts to get a bit cold though the sole of the boot gets hard and does not grip very well. The toe cap would be better if it came back over the toe farther, mine started to tare apart every time I had to kneel down.

I had purchased the same size as I had previously from carhartt but this one was very big on me. My feet were swimming in them. So I returned them.

Excellent boot for all day, all weather use
I've been wearing these for over a year now on an average of 9-10 hours a day. I waited to write a review because I've worn various boots for 20+ years I've been in the automotive industry. I can definitely say this is one of the most impressive and comfortable boots I've owned.

Best snow boots ever!
They are so tough, rugged, warm, dry, and look great. I love how they leave the C imprint in the snow.

Very good for fall and spring. But not very good when it gets really cold. The rubber soles get hard and loose flex when the temp drops below freezing.

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!
Sweet!

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.
