Rugged Flex
 

Carhartt Rugged Flex® technology moves and stretches with you throughout the day so that whatever you're doing, it's easier to do.

Rugged Flex® garments must meet the Carhartt's defined standards for stretch, recovery, and durability, so when you put on a Rugged Flex® garment, you know it won't let you down. You'll find Rugged Flex® in shorts, shirts, pants, jackets, and boots because you need gear that helps you move, not gear that holds you back.

Great pair of work boots, summer and winter.

Best boots I've ever owned!
I've had these boots for 2 and a half years working in HVAC. You can be outside in the snow for hours and never get cold. I've taken them snow boarding and 4 wheeling, they have never failed. I am only here to buy my second pair because the glue around the heel and toe cover is loosened and now isn't water tight. That is the only thing thats failed on this but its been 2 years of heavy work so its well past its life expectancy lol.

I have tried nearly every work boot on the market with 35 years in construction. I LOVE my Rugged Flex, extremely comfortable and they felt great the first time I put them on and felt broke-in. I needed a boot that would keep me warm in the Michigan winter and I could not be happier. Don't hesitate if you are considering these boots!

Was so happy to finally try these out at work. I'm a masonry labourer and spend 10-12 hours a day on my feet in the mud, water everywhere, mortar all over my boots. So excited to see waterproof 400 gram insulation boot that's flexible as well. Bought them on a Sunday, Monday morning ten after 7 my right boot was already soaked after stepping into puddle. So disappointed? It is a great boot when it's dry, loved those 10 minutes I had with them dry?

Disappointed
I have purchased these boots twice before and they were fine for over a year. This pair one hour on the rain and my feet are soaked maybe I have a defective pair or maybe time to switch brands
