I love Carhartt's products. Shirts, Gloves, Hats. That's why I went with the socks as well. I have a size 10 wide foot. These are more than enough long, I'd say 10.5-11 will fill the slack length without stretching sock. But they are somewhat tight around the foot, maybe because of my wide feet? They are built well. But my biggest complaint (and why I rated the way I did) is for the ankle. I don't have big ankles, I'd say average. But these socks are very tight around ankles. Enough to cut off circulation.
