Hi @gi88 . I love Darn Tough socks in general, and just recently took the opportunity to try out their lifetime warranty. It was quick, easy and painless.
I cannot, however, say that I have a favorite style. It depends on what I am doing, and where and when. I have heavy expedition weight for winter. I have thinner ankle height for summer hiking. I have no-show runner-type socks for summer biking. In fact, I think I may have at least one pair of nearly every style sock they have. I even got a variety of different Darn Tough socks as stocking-stuffers for my entire family,
one or more gifts or other benefits from the co-op.
