A few years ago (2009) I bought a couple of pairs of Darn Tough wool running socks. I didn’t know anything about the brand at the time, but they were wool and I had some bonus cash from a company that I needed to spend before it expired. These socks fit the bill of spending free credit (I didn’t even have to pay for postage). I quickly came to prize these socks, which is why I was crushed when a pair developed a hole in the heel. The socks have a lifetime guarantee but I was fairly sure this wouldn’t that wear and tear wouldn’t count for that. So I sent the president of the company the sock with the hole in it and a hand written letter praising the sock and saying I was going to continue buying them no matter what because they really were the most comfortable and durable running sock I had ever worn. I gave him my address just in case he wanted to send me a new pair socks but I wasn’t really counting on it.
Guess what arrived in the mail today? Oh yeah, a new pair of socks and a sticker. Darn Tough Socks are really wonderful.
