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.

Storm Defender®

Storm Defender®, waterproof breathable technology, stops rain, but let’s sweat escape through a breathable membrane—so you can work through a storm.

Staying dry, focused, and safer is easier with rainwear featuring Storm Defender® waterproof breathable technology. It's made to keep you completely protected from rain and amazingly comfortable inside. Work doesn't stop when it rains; it just gets harder.

Very comfortable for long days, quality could be improved a little.
These are great boots. I am on my 3rd pair in 6 years. And I am very hard on my boots. They are very comfortable all day long. They do require some care to keep them lasting, I clean and protect them regularly. My only complaint is the rubber toe protector isn't very durable and the sole started to separate on my first 2 sets, but I repaired them and they kept going.

Durability is horrible
Comfy boots very good while they last. The durability on these steel toes is the worst of all steel toes I've purchased. I've been wearing steel toes for 10+ years and these one lasted 6 months. The part of the shoe where the laces start wears through. If you walk lots or go up and down stairs lots dont get these. I work in a sawmill and I walk around lots , these boots dont last at all.

What length of shoe lace does this boot use?
A shopper on Apr 4, 2020
BEST ANSWER: This will vary on the size of the boot.
Is there regular care and maintenance I need to do?
A shopper on Mar 3, 2020
BEST ANSWER: As with any leather boot, you should always try and maintain the leather. As soon as you've purchased them, treat the leather with a leather conditioner or balm. This will help prevent the leather from fading, cracking or wearing out over time. The balm does not last forever and will require re-application. When this is needed, clean the leather first and then reapply the conditioner. If you do this regularly, you'll wear through the outsole of any boot before the leather wears out. If you're unsure about anything I've said above, look up "leather boot care" on Google and there are tons of great articles that are for more descriptive than this. I hope this helps.
