I bought these socks as a gift for my cold-footed husband, but when he read "wool" on the label, he was concerned they would feel itchy and make his feet hot.  I insisted this wasn't the scratchy wool of our youth, and that he at least try them on.  He loves them!  They don't feel at all scratchy, and although they keep his feet very warm, it's just the right temperature without causing that yukky, clammy feeling that synthetic materials cause.  Amazing.  He says they're very comfortable too - not too tight or loose.  He wears a size 11.5 shoe, and the large-sized socks are perfect for him.  Highly recommended.
