Reviews

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)

Best socks for military use

"Wore these socks all through Ranger School and continue wearing back in garrison. By far the most comfortable socks for both conditions. They dry decently quick and even when soiled still preform better than most socks. Saved my feet in swamp phase where you’re wet everyday for 10 days."

— Riley C. (5/5)

Field or Office - Great for everyday!

"I was first introduced to Darn Tough while shopping for hiking socks and elated to see they have the perfect sock to wear for work with my uniform. They do not fade and they support your arches and heels. I also buy these as gifts to my teammates because they love the quality and how comfortable these feel whether in the field or the office everyday."

— Kristie C. (5/5)

My feet were cooking in

"My feet were cooking in my work boots in the Sonoran heat before these. I’m walking around 5 miles a day with climbing, kneeling, and sitting in uncomfortable positions and my feet are the last of my worries. Not only do they keep my feet cool, they’re comfy, durable and don’t feel overly sweaty. I’ve recommended these to several peers and I rarely talk up a company product. Absolute stand-outs."

— Zach S. (5/5)

Quality Socks Perfect For Rucking

"Darn Tough socks have been beneficial for ruck training and long days in the field. These are the only socks I wear on 12 mile timed ruck marches. I have had zero blisters and they bonus as semi-cold weather socks in cooler weather."

— Alexander E. (5/5)

Darn Tough Indeed!

"I wear these every day normally in a boot. My job entails plenty of walking and I find them to be both durable and comfortable. The quality is top notch as is the warranty. It's feel like Darn Tough dares you to wear them out! It’s all I wear and it performs flawlessly in any situation."

— David M. (5/5)

Top Wear and Longevity

"These are by some way, the most comfortable and hard wearing socks, and I wear them under exact circumstances for long-distance walks in the Highlands of Scotland as well as Stalking Dear across the world. They stand up well to multiple washes and are excellent value given their longevity."

— John W. (5/5)

Wear Everyday

"These are great socks, I wear them every day to work with steel toes and outside of work if wearing boots. They wick moisture away well while staying on your feet without sliding down."

— Kyle F. (5/5)

Great product! Durable and are better than other brands.

"The Green Tactical Boot Socks Midweight are great for duty as well as Drills. Breathable and a lot more comfortable."

— Evan F. (5/5)

I literally cannot say enough positive stuff about them. buy multiple pairs if you can."

— Cody R. (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!
