Men's composite toe astm 2413-11 eh 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! ## Features - Composite safety toe - lightweight, non-metallic, and non-conductive to heat or cold.

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. ## Frequently Bought Together - Carhartt Men's Rugged Flex Wp 6-inch Composite Toe Work Boot - Carhartt Men's 6-inch Energy Black Waterproof Composite Toe Cme6351 Industrial Boot - Carhartt Insite Technology Footbed CMI9000 Insole --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/15765384-carhartt-mens-cmf6380-rugged-flex-six-inch-waterproof-work-boot](https://www.desertcart.hr/products/15765384-carhartt-mens-cmf6380-rugged-flex-six-inch-waterproof-work-boot) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
