Between a regular sock and a short sock, ankle socks clothe the feet and ankles but leave the legs bare. Ankle socks are for golf and some other games and sports, fitting the usual size of sport shoes without restraining legs' movement.
Some ankle socks are also vintage ladies' dress socks with lace tops. Ankle socks come in all sizes and many colours and designs. On the green or on the dance floor, clothe your feet in ankle socks.
