I am middle-aged and have been a very picky sock shopper since I was old enough to buy socks. I have always been active and have always been prone to calluses, especially on the top and bottom of my toes. These are probably the most comfortable socks for my toes that I have ever worn. Just like shoes have a left and right shoe, these socks have a left and right toe. They cover your whole leg. I can't rate their durability as I've only had them for a few months, but they offer maximum comfort and support. I just bought three more pairs.
