Review: Approved for rooftop work - The Rugged Flex feature is a game-changer for climbing and kneeling, offering almost immediate comfort with no painful break-in. Most impressively, the traction is outstanding. The outsole grips tenaciously on wet surfaces, morning frost on roofs, and slick concrete, which is a major safety and confidence booster. Compared to my older, heavier boots, these feel significantly lighter, reducing leg fatigue over long days of climbing up and down ladders.
Review: Great Boot !! - It is Jan. 5, 2020... I bought these Carhartt's in Feb. 2019 and I really am impressed with these Boots!! I have worn Timberland Boots for so long and became so concerned about their decreasing quality... I would normally have to replace my Timberland's about every 8-months, mainly because the Water-proofing would fail & the leather would also tear or rip. These Carhartt Boots show less than "half" of the wear-n-tear that the Timberland's would normally have at this age. The entire boot is still fully intact and "nothing" has become detached or loose. The soul is still firmly bonded to the boot without any failure anywhere! They also still remain exceptionally "Water-proof"! Virtually nothing has worn out on these Carhartt boots. The inner footliner has not flattened out or become hard, it's still comfortable! The only thing I've replaced was a pair of boot-laces last month! And the best thing... these are a lot less expensive than the Timberland's that I'm used buying! I will buy more of these!! Highly recommended !! UPDATE: On May 22, 2020 one of the boots finally leaked and got my foot wet. Am I upset... NO! These boots have outlasted every pair of Timberlands that I've "ever owned"! Outlast them by 7-8 months! The carhartt's are still very comfortable, there is no visible damage or tears in the materials, the souls are still very much intact, they just have a small leak now. A lot more than I can say for Timberland. I'll definately continue to buy Carhartt boots!

## Questions & Answers

**Q: Are these insulated?**
A: No

**Q: Fit true to size? I normally wear 10-10.5.**
A: If anything they are slightly bigger.  I always were a size 13 sneaker but my 13 boots are a bit loose.  I probably should have gone with a 12 but I make due.  I wear very thick socks and it makes up for it.  I would recommend going to a store so that you can actually try them on.

**Q: Tiene punta de metal? Y si no, de que es? Es dura?**
A: Si tiene una punta muy dura creo que si es de metal , son muy cómodas  te las recomiendo

**Q: Are the soles electrically resistant?**
A: Yes this style offers Electrical Hazard Protection.

### ⭐⭐⭐⭐ Great fit. Comfortable.
*by O***Z on June 19, 2025*

Everything about them is great, except on the rear seem, I don't know why it started doing it. And it ripped right at the seem. The size chart was spot on for me. The toe comfort was large so it does not feel tight even with thicker socks. The impact resistant is really good, even side wall. Over all its an amazing shoe, just ripped on the heel right on the seem. But even with that it still performs. Also they are a bit on the heavy side, and great at keeping water out, good slip resistance.
