Reviews

Not matter the heat maintain dry feet!

"Always trying different Darn Tough socks out in different situations. We are repairing work in a steel mill. The air temperature is around 115 degrees plus the work we are doing . The only dry part of myself was my feet."

— Kevin C. (5/5)

Socks are great. I wear

"Socks are great. I wear them in Danner side zip boots, and my feet have never been happier. The elasticity has started to relax but overall, still very happy."

— Michael T. (5/5)

The socks fit well and

"The socks fit well and the cushioning makes a big difference during long work days. These are a replacement for the socks from military clothing sales that finally wore out."

— John L. (5/5)

Headed on Deployment w These

"These are the best socks to pair w combat boots! I have worn them everyday I am in my boots. Great cushion. Excellent wicking on hot days. I bought 10 pair and gave away my other socks. They keep my feet feeling great, which brightens my day. My mascot “Little Wrigley” likes them, too."

— Tobias (5/5)

T4021 every day work sock

"I work all day in these, whether I’m on the farm in the sun, in the car shop, out on the town, these are my go-to sock for everything, every day, 7 days a week! Amazing quality and perfect for what I need them for"

— Corey B. (5/5)

Great duty socks

"These are excellent socks for LE/MIL duty. They wick moisture well and have just the right amount of cushioning. I will buy again."

— Douglas C. (5/5)

Darn Tough is the only way to go

"I love all my Darn Tough socks. Wool is where it's at, and Darn Tough has got it figured out. I've had some other brands, and while they are still good, I prefer my Darn Tough socks. I've got my husband hooked on them and I'm trying to switch my kids over to only wool too. One of my favorite things is that I don't have to pack as many socks when I am traveling or going out of wildland mobilizations. I on wildland, I have to have enough clothes to last 2 weeks, and now I only bring about 5 pairs of Darn Tough for my socks. I let them air out for a day or two before re-wearing, although they really only need a few hours to be good to go at least as far as smell and comfort go. I do the same on trips, and they get much less disgusting during my typical travel."

— Samantha D. (5/5)

These socks are very comfortable

"These socks are very comfortable the quality is top notch. Customer service is very friendly and helpful as well."

— David N. (5/5)

Pure Magic

"I'm not sure what it is about these socks, but I can ruck further while wearing them. I have another pair of socks from another well known brand, and with those the bottoms of my toes start to hurt after a long time rucking. With the T4021, my toes don't bother me. It's like after 20 miles I still have a spring in my step. I wear these socks every day, I mean literally the same pair. I wash them and let the socks air dry every once in a while. I own the socks in black, Large, in case you don't know what to get me for Christmas. These socks are like no other."

— Noah (5/5)

Performs as Promised

"My coworker recommended Darn Tough with the promise that we can wear them multiple days without stinking. I was skeptical but tried a pair. It is true! Now I can save room while packing! Next, I plan on experimenting with their sports socks. Less socks, less laundry."

— Robert C. (5/5)

Q&A

I would like to buy a pair for my son but not sure he will follow the washing instructions. Is that a problem? Will they shrink? Thanks
If the socks are washed using water that is too warm or dried with too high heat, then yes the socks can easily shrink.
Hello - what would you recommend for a female (slender - 120-125 lbs) size 7/7.5 women’s shoe? ROTC cadet. Should it be tighter (xs) or bigger (s)? Don’t want it to bunch too much!
Hi BB! We recommend a size small. We've found that customers who fall on the upper end of a size run do choose to size up due to the snug, performance fit of our socks.
Would these be good for an Alaskan hunting trip in the winter or great lake winter?
Yes! A midweight sock is a great option and another option would be a heavyweight sock to keep you warm.
T4021 how much does one pair cost?
Hello, A pair of T4021 costs $28.00.
Would these socks be good for South Floridian weather, to use with work boots? (Hot and humid). What about with wingtip dress shoes?
Hi Zac! The T4021 is a midweight option that will work well in a variety of conditions! We use wool for its amazing natural properties including temperature regulation, odor resistance, and moisture wicking. These will work very well in work boots but might be a bit too much volume for a dress shoe. We know it can be tricky to shop for socks online so we got you covered with free return shipping for exchanges or returns for 90 days on all orders placed on our website, just in case!
