Work
I bought them for my husband for work; he says they are comfortable and very lightweight—unlike the ones he had before, which were very heavy. A good choice

Better than most I have had.
Well I like the comfort of this boot. Which matters when you are on concrete for much of the day, I am using them on 59 year old feet and with that will always have times that during the day are uncomfortable. Still i do like them somewhat. They offer some cold protection only I noticed cold will work through from the soles, I was standing in place outside for a time yesterday and had to keep shifting weight and lifting my feet because the asphalt was freezing cold. Once you are moving everything seems okay. I coated my boots with mink oil since its winter in New England and our warmer winters are bringing a more wet snow than used to be. (This was just to add a second outside layer of water protection). I work from on my knees quite a bit and the sole of the boot has an extra flex feature which allows the foot to curl up more than conventional boots which is good for overall comfort while performing on the ground work. Will mention that they do come large in size and I plan to buy more pairs while dropping down a half size at a time until they fit to perfection. I will use this larger pair for winter to allow room for thermal socks and use a tighter fitting pair for summer work with lighter weight socks. I would buy more pairs because I will always need more work boots.

Great Boots!
My first pair of boots, and they are awesome. They're comfortable as hell (although they squeeze my toes together a little, I've gotten used to it though), and they seem pretty durable. I've had them for 8 months and there are no real damages to the boots itself, laces haven't fallen off and the sole is still attached. They're a pain to clean but man are they handsome when they are, unless you don't like markings which there are quite a few of on them. I wear them casually and I get compliments all the time. Favorite thing about them is the rubber over the steel toe. It prevents a lot of scuffing to the leather which is left exposed on many other boots. I'd recommend them any day, although I can't speak for their performance "on the job" they do meet the safety standards. If you're wearing them casually you'll definitely wear them past their price tag. P.S. Screw Timbs

Interior lining degrading
I’ve been wearing them non-stop for about 2 months now. They are comfy, better than the ones the company is giving us, but I expected more. They run true to size I’ve noticed this morning the interior lining behind my ancle is staring to tear off. We will see how long they last I work as petroleum engineer, but last couple months I’ve been preparing tools at the shop so mainly hard floors. The rest of the year is going to be at the field so we’ll see As for the thermal protection I did take them for a 1 day trip to field on about 30 ish C temperature and didn’t feel uncomfortable Good purchase overall I’ll try other brands next time I buy boots

EXCELLENT safety boots!
These boots were ordered because I injured my toes cutting wood after Hurricane Sandy felled one of our trees. I was using safety equipment while using my chainsaw (helmet, visor, safety gloves, chaps) ... but didn't have steel-toed boots. I was basically wearing sneakers when a heavy log fell on my foot. Anyway, I purchased these CAT boots based on the reviews, description, and Caterpillar's reputation. At first I thought they would be too large (I wear a 9 wide), but after putting on heavy socks and tightening the laces over the arch (first 3 or four loop-holes), the fit vastly improved. My toes have alot of space, and there's absolutely no rubbing, and after wearing them ALL day, they felt fantastic. No breaking-in needed (in my case). I don't know much about safety boots, but these have a loophole (fifth from bottom), that seems to allow you to snug-tighten the laces without hurting your feet, and allows flexibility around the ankle. The sole has a very solid and secure feel--no slipping at all. I was stepping on sharp rocks and felt absolutely nothing on the soles of my feet. I should have purchased these years ago. The only negative (and this is not really a criticism of the boots) is that the sole treads are deep and capture dirt and mud. You can't walk in your home with these even if you wipe your boots on a brush/scraper. Again, this is NOT a criticism, but expect that they will catch dirt.

The only Boot we'll buy
We are farmers, and my husband is HARD on his boots. We have bought all kinds of brands through the years, but once my husband found these, this is the only one he'll let me buy. He wears them HARD, as you can see in my picture. Eventually they do need to be replaced, but they last longer than any other boot. He typically does get a full year out of his boots before we have to replace, which for our work, is really good. We've purchased these boots at least 4 times now. He says they have great support, don't get TOO hot, but can also wear them in the shop in the winter without being too too cold. The soles & rubber stand up to tough work, and even in wet weather don't soak his feet. Highly recommend.

Money well spent
These are very comfortable and well-built boots. they took a little breaking in, but that was to be expected. I will need to wear these every day and anticipate no issues.
