Thorogood Bunker Boot


I'm very pleased with this item.

Thorogood 14"" knockdown elite boots


These boots exceeded my expectation and are far better than my old rubber boots. They were a little stiff when new but wear in nice and are very comfortable. The siping on the soles is nice and provides great grip. I highly recommend these boots and will definitely be buying another pair when these wear out!

Not a bad boot


I liked this boot with our recent tests. But it was heavier and less confortable than my favorite pair. Also, I was surprised to see that for a boot of this price the liner wasn't even a Crosstech.

Feels like a custom fit


Love these boots. Foot locks into boot for a snug fit. Awesome support and protection all around. Great side tread for crawling. They do loosen up after they are broke in, so don't let a slightly tight fit around the foot and ankle scare you. Comfortable liner that doesn't detach and fall down like many other boots that the guys have. Very comfortable boot all around!


"Is this boot also certified for proximity firefighting?"

Hi Andrew, I checked with Thorogood and here is their response: ""It is certified to NFPA 1971 and NFPA 1992. It is not technically a ""Proximity"" boot.""

"Does the sizing generally run big or small? I have a pain of 13.5 W rubber boots that fit perfectly, but I normally wear size 14 shoes. I am nervous purchasing a pair of boots without trying them on."

Hi Greg. Thorogood recommends you order a half size up. So if you normally wear a size 11 shoe, order an 11.5 boot.

"How much does it weigh?"

The boots are running anywhere from 4.5 Lbs. to 5.5 Lbs. pending on the size will also need to considered.

"Is this boot streamlined and lightweight??"

Sean, good morning, I wouldn't say they were lightweight, about 5.5 lbs. depending on the size, they have tried to make them more comfortable to wear, and they still meet NFPA 1971-2013 standards

"I see you said to order a one size bigger the what I normally wear (example I wear a size 13 you said order a size 13.5). Now what if I do so and the boot is to big what happens? Can I return it for the right size?"

Yes you can return them for a different size, as long as they don't show any wearing them on the outside, or any marks / signs of being worn. Sole cant have any dirt or anything on them

"Is there a version for women? I want to order the correct size and have ordered boots through this maker in the past."

Wina, use this part number 504-6389-XXX with your size and width, this tells them it's a women's model boot. the ""504"" indicates that it is a women's boot, where as a ""804"" is for the men's boot.

"I have purchased a pair of Thorogood Men's 14"" Power HV Bunker Boots and they fit good but after a few fires they started to feel really uncontrollable in toe's. I am looking into buy the Thorogood: 14 Knockdown Elite structural bunker boot. But I am hesitant that it will happen again. Also I wanted to see if you have any store programs where I can trad in my old boots and pay the differences in the boots."

First Moises there are no trade-ins, ok, how old are these boots that you say your having a problem with the toe? Maybe if there is a problem with them Thorogood should see them (this will depend on how old they were) The boot has a safety composite toe, there has to be a reason behind this, you don't want to purchase another pair of boots and have the same problem.
