These are much smaller than the wool socks I bought from them previously (XL). Size 13 shoe, in the middle of the size range. These would be comfortable if I wore a 10 or an 11. I gave them to my wife.
Pros
First socks I had that didn't work their way down around the heel of my foot when wearing....
Cons
Even though the size chart was followed, the toes were tight and constrictive.
