These socks appear to be of VERY good quality. I usually buy damn hard, point 6 and chic wool socks. I have several Meriwool shirts and I really like them, so I decided to try the socks. Out of the box these might be some of the highest quality socks I have ever owned. I didn't put them to any test other than unpack, set up and go to work. Time, some laundry, a few hikes - this really is a melting pot they haven't seen before. So far I'm very impressed.
