Nice medium weight wool socks. They are warm, comfortable and durable. I like them so much that I bought more. I work outside in Wisconsin winter and have no complaints about these socks. Some other wool socks are so bulky that they don't fit in my boots and make my feet sweat. The last thing I want is wet feet and socks at work all day. These socks breathe well and are the best for my use. They can also be machine washed. I air dry them to prevent shrinkage.
