Great product. For winter boots I will only buy these
The price is a little steep, but if you want your feet to be warm and dry its worth it. I work outside year round, and these are amazing in the winter. It's currently -5 out and I only have one pair of socks on with these boots

Work boots
These are very good work boots. My husband is on his feet long hours during the day on his job and he wears these even after work. Very comfortable and not heavy. He loves the composite toe as well. Says you don’t even know it’s there. Very durable. Last long…

Great boots!
I will be the first to admit that when I typically buy something I need I go with the cheapest possible solution. There are exceptions to this but footwear has never been one of them. I work on a farm so my boots take a beating. Usually I can get about a year out of a $60 pair from walmart. This year however my new pair didn't even make it a year, the interiors wore out and I was getting blisters and places wear it was rubbed raw on my feet. So I gave in, did some research into some more quality boots and gave these a shot. I have bought Carhartt coats and hats before and know what a quality brand they are. I will go beyond saying that these are the most comfortable boots I have ever worn and say that they are the most comfortable footwear I have ever owned. Even when I put gel insoles into the other shoes/boots. I've already put them through some paces testing out the waterproofing and composite toe and they did not disappoint. My feet remained dry and safe. When combined with a pair of the Carhartt Men's Force socks they feel amazing. I worked a 13 hour shift doing a multitude of things and being on my feet all day. Climbing on and off trailers for a good 7 of those hours. And ONLY THEN did my feet really start to bother me at all, my feet would have been dying by the end of that in my old boots. If these last for a few years then I definitely know what my next pair of boots will be.

Terrible quality
I’m a contractor and good boots are essential. These however fell well short of that. After not even 6 mths the soles on both boots came completely off. I used to love all carhartt items but the quality overall has declined exponentially.

Just bought them. So far so good.
9-5-18 Boot fits with wiggle room. I bought wide because I have a wide foot. If you do too do not kid yourself and also go wide. I bought inserts thinking they would be okay to wear with the original boot inserts and its not a good idea. Thats what I did with my last pair of work boots. You do need to break them in a bit but hopefully that happens soon. They are lighter than most others. I read they were pretty well made and that they were waterproof. I havent tested them out yet and will not intentionally but when the time comes I will update this review. Til then.

awesome
Usually it is difficult for me to find work boots in my size (men's US 6-8, depending on the brand / fit). Arrived just in time for a cold snap! I work construction, and we work through most of the winter, so insulated, water-proof boots are a must-have for me. There was a bit of chafing for the first week around the back of the leg area (through wearing wool socks and tucking sweatpants and thermals under the boot cuff), I think because I'm not used to wearing boots this high, but the extra support around the leg / ankle is actually pretty nice. Still flexible enough to crouch, kneel, and crawl around for extended periods of time, too! My toes only start to get cold after several hours in negative degrees, with windchill, and haven't been numb or excruciatingly cold at all yet. The sole is fairly grippy. I have slipped on the ice, but only fell once, when I'm usually on my ass multiple times. It does seem like some cold water / snow is able to leak through the lace area, but it's never been really noticeable, and may just be my sweat hitting the cold air when it finally makes it through the boot.

Warm, comfortable, well made
Great right out of the box. Definitely didnt have that dreaded "break in period". Couple of hours tops, and they feel fantastic. The wides are an actual wide, Love it. The composite toe makes for a nice lightweight that also doesnt feel as cold as a traditional steel toe. 27 degrees out earlier, feet felt plenty warm. Will update on the warmth and water resistance after some real winter conditions soon. I have no doubt on them being fine down into single digits, and tromping around in mud and snow, but we'll see soon enough.

Heavy Duty
These Carhartt boots are the real deal. These are not cheaply made. The only downfall that I have to say are the strings. They are a little thin and not for this type of boot. They need to be thicker. Other than that these boots can handle it. Great protection for your toes and great support for your ankles. They look great and wear nicely. Like any footwear when you are going to be on your feet for long periods of time, be sure to add a pair of insoles. That will help in the ease of use of your boots and your feet and legs.

Excelentes botas para trabajo. No las recomiendo para campo por el peso y el casquillo. Aún así son unas botas muy cómodas. Pedir medio número abajo.

Very comfortable boots, warm in the winter and not to hot in the summer. great laces. Had them for almost 8 months now and they have yet to show any wear and tear on them. (I'm hard on boots)

I hate to say this, but they’re a terrible boot. They’re fine when they’re dry. The second they get any moisture they just they deformed the constantly stay wet after that despite putting the proper conditioners on !! Wish I could recommend,just can’t do it 👎👎
