I have worn these socks for years. Very warm and comfortable. But... the latest pairs I purchased were way, WAY too small for my men's size 11 foot, despite all of the socks labeled large. I managed to get one on, but the sock's heel was several inches short of my foot's heel. I could easily see my foot through the sock as it was stretched so tight. I returned them and may try a pair of extra-large.
I used to wear wool socks only when necessary (i.e. with hiking boots, very cold weather, etc.). But these socks are the BEST, and I wear them all the time, especially just lounging around the house. Well, not so much in the summer. Great around the house, and the BEST part - easy to wash, and they DON"T ITCH!!!
