Darn Tough warranties their socks for life. I wear size 10 shoe which is large sock size. I have several pairs of large Darn Tough socks that fit fine and I have some mediums that fit fine too. But one style of their large sock was too big--it puckered at the heel. Contacted Darn Tough and they said send them back. Did and received a warranty credit and ordered another pair and had them in 3 days. Great service and great product.

And made in the USA.

Wool?

They have socks for hunting, hiking, running and cycling, I believe. Great socks. Great wool.

PA Frank---Most of their socks are merino wool. I find it comfortable and no itch. Go to the Darn Tough site and they have a video about where they get their wool.

Darn Tough is about the last of a dying breed when it comes to customer service and backing up their product.
