Familiarity: I've put it through the wringer
Socks was never something I cared about. I wore the oldest simplest socks for the longest time. Unfortunately, I started walking the luxury sock path and now my my feet are pampered whiners. I picked these up because they are some of the cheaper merinos out there. They're comfy but they seem to fall off the back of my heel often. Other socks I've used don't. I'm a solid size 8 and I got the S/M so maybe I'll try the M/L to see if I have better luck. You can't beat the price.
