Excellent Boots
Love these boots!!! The quality of construction is evident inside and out. I got the ceramic toe and the weight isn’t bad. They are very stable and protect against foot roll on uneven terrain. All day comfort!!

Great boot. It would be even better if they made it with insulation as I prefer a 6” high rather than 8”. You can get the same boot with insulation in an 8”..

Lightweight
Write your review here. It must be at least 10 characters long. Overall, Great boot, very comfortable and light weight. My third pair. They lasted each approximately 18 months. The stitches on the right boot come apart, and a hole appears on the flex leather, in same spot on both boots. I work in HVAC cellar boiler rooms. I wish they were more resistant to water. Maybe I need to look into boot warmers, to help keep the boot fabric and stitches from breaking down., because they will absorb water like a sponge and negate the electrical protection. whether you would recommend this product and what you like or dislike about it.

What can I use to clean them and still keep that dark brown oil tanned look?
A shopper on Jan 22, 2021
BEST ANSWER: I just use warm soap and water to clean them. Then i use a good boot oil or PB Blaster or i brush them with motor oil to maintain the dexterity and kerps them waterproofed as well.
What type of shank do these have?
A shopper on Nov 3, 2020
BEST ANSWER: The shank on the CMF6380 is fiber glass.
Will these boots pass a metal detector?
A shopper on Apr 17, 2020
BEST ANSWER: Being a composite toe, I would say yes, however, I've always been told to remove my boots (i.e., at the airport) prior to entering a metal detector.
Are these boots good for landscaping?
A shopper on Feb 19, 2020
BEST ANSWER: I would say it depends on what you are doing in landscaping. I am a truck driver that hauls heavy equipment. I was going through 3 pairs of Timberlands a year and decided to try Carhartts. I need to bend down a lot and my shoes were separating in the middle. The Carhartts do not do that. 1 pair of Carhartts lasts me 1 year. If you need a shoe with good flex I would highly recommend Carhartts. Also extremely comfortable. Hope this helped. Good luck!
What’s better steel or composite protection from something falls on your toe?
A shopper on Dec 5, 2019

Are these boots really waterproof?
A shopper on Nov 23, 2019
BEST ANSWER: I have owned 5 pair of these boots and yes, they are waterproof up to 1 year. I wear them 5 days a week, 9 hrs a day and work on a golf course. They are the best boots I have ever purchased and would recommend them to you. But, as I said, 1 year. I have had 2 pair replaced just prior to the 1 year of purchase date. Keep your receipt!

would you recommend these boots to someone who works in roofing?
Catalina on Nov 28, 2016

My floorlayer husband loves these boots, they're comfortable, and don't stink at the end of the day. He wears them out extremely fast though. The soles have seperated from the bottom (which he has reglued multiple times) and of course the steel toe is showing through (normal for carpet guys) Do you make a shoe that can handle the wear and tear of a floorlayer?
