First of all the socks are great First of all the socks are great! You get the quality you pay for! While most companies won't live up to their grand guarantee claims, Darn Tough are leading the way! When a pair of socks started to develop small holes after three years I filled out the online form, to be honest I was really expecting them to be "Unconditionally Guaranteed for Life". However their customer service made contact very quickly, and with some simple instructions to follow the socks were then replaced. I was very impressed that they stand by their products to this level and honor their warranty, so I also bought another pair. Very happy customer indeed! :)

Most comfortable and resistant socks ever! I have never had socks as comfortable and resistant as these. I have several pairs and only one has started to show signs of wear (after heavy use) but the advertising around the lifetime warranty is not misleading; it was very easy for me to contact the after-sales service who were quick and extremely friendly to have a new pair sent to me. The icing on the cake: I was offered the option of choosing another model if I liked it and it was not necessary to return the defective pair. A very positive experience. The investment is totally justified! I don't think I'm going to buy any other brand of sock than Darn Tough from now on. Well done!

Not set up for proper Uk trading Wonderful socks, but I got charged £114 by FedEx for customs charges and Darn Tough were unable to resolve this. I bought the 4 pairs of socks from the UK website, paying UK delivery charges, as a Christmas present. In late Jan I then got issued with a charge for unpaid customs charges by Fedex. Despite having tried multiple times and ways to get this repealed since then (and to do Darn Tough uk justice, they attempted to help), it was impossible, so I have ended up paying £114 to FedEx’s debt recovery agency as they would not respond to my emails themselves. While this may be have been partly a FedEx issue, Darn Tough were not set up properly to prevent this issue. I recommend avoiding buying the socks directly from the website and find a UK retailer. The quality of the socks themselves is terrific.

With all of the hype With all of the hype, these are simple sweat socks, softer than many, and way overpriced - $22 for a pair of sweat socks?! - with all kinds of gimmicky sizzle.... and the prices go up from there. Granted they are made in the USA, and that is important to me. Still ... almost as happy with socks from Costco where I can get six pairs for that amount. Although I'd rather buy American, as long as they are NOT made in China, North Korea or Russia .... I'm fine

Great socks Great socks, but the thinner variety has ripped for me. I know they have a guarantee on their socks, but I've just kept a pile of the ones with holes for me to one day try to get fixed. Love the materials and they ARE quite tough, especially the thicker socks.
