What material are these made of? I used to wear smartwool ankle socks but they stopped making them. Not a fan of the 100% synthetic stuff.
You need a NIP-05 my friend. Wanna be "seth@sdbitcoiners.com"? 
Best socks ever!
I used to have them, but today I only have some stamdard Marino and 98% I am Barefoot....
