Familiarity: I've put it through the wringer
These are some of the most comfortable and durable socks I have owned. The support is perfect the thickness works great for me. They are warm and the venting on the top has kept the sweat factor down in all climates when coupled with an appropreate eVent or GoreTex shoe or boot.
I have had these now for 4 years and they are as comfortable today as the day I bought them. The elastic is holding up to the point that they still feel as new as the day that I opened them. Daily wear, Back packing the AT or just about anything you would throw at them these are my go to socks!
