Review: 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
Review: 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!
*by N***D on August 2, 2017*

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
