Socks had already been worn when my husband commented that they were fgairly tight.  He didn't want to tell me since they were part of a gift box.  I ordered him more in a larger size and they are perfect.  He wears a 9  1/2 shoe and needed these in extra large.  They are excellent qualiuty and very comfortable.  I inherited the old ones.  I have a size 8 woman's show and needed the large men's socks he had.
