These socks use combed cotton yarn, which is a very soft version of regular cotton. Combed cotton doesn't have any impurities or short protruding threads, is stronger than regular cotton, and is made by treating the cotton fibers before they are spun into yarn.
Don't hesitate! These combed cotton and synthetic socks will be a go to #1 sock as my Minnesota weather warms up. The craftsmanship is second to no sock I have ever owned. The 3/4 length sock fits and stays as I have always wanted socks to behave. Superb!
The most comfortable socks I ever wear. Great quality and great style.
