These are very comfortable, not too thick, and the right length - not over the calf, but high enough to give coverage between my shoes and my pants hem, even when I sit. I am happy to have some color choice also. I gave 4 stars instead of 5 because I would love them to be thinner and dressier. Seems impossible to find a comfort sock that is not more sporty than dressy in appearance. When you have to wear them everywhere, sometimes you need a dressier look. That aside they are 5 star.
