  • Best socks I have ever owned
Size: Large Color: Black
I got 2 pairs 3 years ago and bought 5 more this year. The only way to tell which pairs are 3 years old are the ever so slight fading on the Darn Tough branding. The black hasn't faded and the fit has stayed the same. They don't slide or bunch even working in a factory 8-10 hours a day in steel toe boots. They are soft and comfortable even the ones that are 3 years old don't feel any different than the brand new ones. They don't make my feet sweat even in 100°+ heat and in winter my feet stay warm. My coworkers think I am crazy for spending so much on socks but my feet don't hurt at the end of the day and even when soaking wet I am not uncomfortable. Worth every penny and if I do ever need more than a week worth of socks I will buy more. I do wish they were a little higher up my leg. The Steely might have been better for the environment but I wouldn't trade them for anything. ... show more

  • So great they got stolen
Size: Medium Color: Coyote Brown
someone stole these from deployed marine I sent these to in a care package DURING HIS FIRST WASH :((((( We’re terribly disappointed someone eyed these fantastic socks and actually stole them during his laundering of our of his washer or dryer between uses. Please keep these safe and add labels if sending to someone who does laundry in shared spaces :((( I guess this shows how amazing these socks truly are at the same time. They were going to be his second pair and he’s been loving his first pair for a good 9 months so far. They are durable and highly effective preventing foot pain and suffering for those that push their physical limits regularly for their job. I guess I have to spend another $30 bucks on these thick and moisture wicking cozy high quality socks… still worth every penny. Darn Tough, please help me replace or fund the marine cores addiction to your socks!!!! They need khaki or black only I believe! ... show more

  • Absolutely worth the price
Size: Medium Color: Black
Nothing but good things to say about these socks and this brand. I have a quite a few socks from them and I will only buy Darn tough again in the future. The socks are very high quality and keep my feet plenty warm. I'm not in a super cold environment but I do work outside in borderline freezing weather. The sock is not super thick and give you decent grip for a wool sock. They're plenty comfortable, being worn for 10 hours shifts mostly standing. Darn Tough also have an excellent return policy. I will be buying more. ... show more

  • Best socks I have ever worn
Size: Large Color: Black
Best socks! I used get Bombas and they are way too thin and get holes way too fast. These are worth investing in. My feet would smell and sweat in cotton socks. I got 7 pairs of the low cut socks and have worn one pair every single day for the last two years and none of them have holes. I no longer have smelly feet and my feet are not sweaty. I have a pair on as we speak. The size is good, moisture wicking for sure, they look good, they're soft, stretchy but still compress very well. They also have heavier weight if you want them. Get them! ... show more

These are the only socks that my son-in-law will wear. He says they are very comfortable and warm and lasts a very long time.

  • Investment
Size: X-Large Color: Foliage Green
Great sock. First time buying and won’t be last. I’m just in between on sizing so that’s the hard part. Quality of the product is great. Lifetime warranty is the best part as well. Elevate the level of comfort for your feet.
