Thin comfortable trouser socks help protect your feet while adding some colorful style to your wardrobe. Trouser socks are designed to have the cuff rest just above the calf muscle and just below the knee. The thin nylon/spandex blend helps to protect your feet from rubbing in your shoes, while still allowing you to wear more narrow shoes than traditional socks would. Case includes 48 pairs of one-size-fits-most ladies trouser socks assorted among gray, brown, navy blue, and black.
