Really! I have heavy calves and regular women's socks leave marks on my calves.  Large women socks fall down.  I accidently wore a pair of my husbands--they fit great at the calf but were too long in the foot bed. I  wear a size 7 shoes.  I purchased these to see if they would work,  they do!  I would gibe 5 stars if I could obtain other colors (grey, charcoal, plum).  Hope this helps another woman with 'solid' calves like mine!
