I’ve worn mine long and hard and haven’t gotten to test out the warranty yet, the first pair I bought is probably closing in on a decade and nearly indistinguishable from pairs that are several years newer. Even if they don’t honor their warranty for some reason I feel like I’ve gotten my money’s worth and then some.

I want to point out here, in Australia there is a brand of socks called Darn Tough that is sold at Kmart, Target and BigW, it is NOT THE SAME Darn Tough brand you see raved online. It’s a completely different sock brand thats been around for about 20 years in Australia and just happens to have the same name. They are not great socks, very thick but don’t last long.

Do you use those for everyday wear?

Bought 2 pairs of their normal socks (everyday/sport socks) because they advertised to keep your feet cool during the day. I decided to test them out before I bought a bunch as workout socks.

1 was completely ripped on the sides by literally the 3rd wear (2nd week I had them), only walking around the office a bit.

The other lasted 8 wears before it got a hole on the balls of my feet and was almost worn through on the sides (about 6 weeks), still not one workout done with then

By very far the worst socks I have ever owned. I didn’t get a chance to try their warranty because I moved out of the US, but hot damn I will always recommend against their thin socks, only go for the large tube/hiking/warm socks.
