Im 62, 203 lbs and I wear a size 13. These socks came up to my to just above my knees. They are snug, but not as tight as compression socks. From my heel to the bottom of my knee is 22 inches(or 56 cm.) my calf widest girth is 18 inches (around 46 cm). They are a little thinner than your standard tube sock, but still have a sock appearance. Wore them once to a dance party and they stayed up all night.
