Things We Don't Cover

We get it, the idea of “unconditionally guaranteed” could be interpreted differently, but we guarantee our work, and our socks. Hike to the Moon, and we will cover that kind of wear, but if you leave them there, we don’t want to assume responsibility for that. We don’t need a receipt, we don’t need a reason – although we do like to see them, and if you want to share a story, we are always curious. In the meantime, these are the most common questions we can answer:

Dog eating a sock, something our lifetime warranty doesn't cover


We can only speak to the sock itself, not dogs or other means of devastation brought on by not wearing the socks on your feet. They are not trailer tie downs.

A pig roasting over a fire - not something to do with your socks


Merino Wool is naturally flame resistant, but fire can be avoided. They will survive a brief encounter with flame, but they won't save you pain from a fire walk. Nor will we cover that.

Lost in Laundry

We only warranty pairs, not singles. There's still a good chance they are hiding in the pant leg or sleeve. Regardless, loss is not something we can prevent on our end.

"I literally only own Darn Tough socks. I kinda want to see how good their customer service department is, but their durability prevents me from it."
