These socks are great. These are my first Merino wool socks. They are quite soft and not itchy at all. They seem to have just the right amount of cushioning. I was afraid that they would get too warm for me. But although my feet stay warm, my feet don't get sweaty or wet like cotton socks sometimes do. I usually wear size 9.5-10 shoes. Medium socks fit perfectly. The top of the sock is right on my ankle. TO UPDATE. After about a year of wearing these socks, both pairs developed cavities in the toes and bottom near the balls of the feet. Back then, I usually only wore these socks two days a week. Too bad they just didn't survive.
