I wore my new merino wool socks all day today. They were very comfortable. It’s hard to believe that wool socks can breathe enough to make your feet comfortable on a hot summer day but it’s true my feet sweat but the wool socks moved moisture away from my feet and I was totally comfortable.
I’ve read that wool socks are also better than cotton socks for travelers because you can wash them out in a sink and hang them up overnight. In the morning they are supposed to be dry and ready to wear again while cotton socks will not dry overnight.
