Great socks! I would recommend going very large, even if you actually wear large ones. I personally like socks that are just below the knee. Because it's wool, it will shrink a little when washed. I think sizing is a matter of personal preference but these are quality socks that are comfortable, feel firm to your feet, they don't slip, they don't fall to the ankles like some socks do. I highly recommend these socks. Buy a few, try them, but I promise you'll fill your drawer with them.
