Reminder to please not abuse Darn Tough's warranty everyone!
i.e. if you find a pair of darn tough socks at a thrift store for $1, cool great find! Enjoy your almost free, very long lasting pair of high quality socks. But that does not entitle you to turn around and return those socks for a warranty on a brand new pair forever.
People abusing warranties is how every lifetime warranty eventually gets gutted. So if you like the socks, support the brand so they stay around awhile.
P.S. they are Made in Vermont
Ah okay thanks I'll do some searching
