I started buying Darn Tough brand socks, apparently have a lifetime warranty, haven’t needed it, but can’t imagine shipping them back unless you had enough to space out shipping costs.
Made in Vermont, I like them.

Lately I buy a whole bunch of the same sock and use the old ones to put treatment on tires and then toss- life is too short to try and find the matching sock. Got a bunch of white athletic all the same and then enough black Darn Tough socks to get me through a work week.
