12 pairs of ankle socks for women. All black all matching. The nightmare of sock matching is over. Our 12-pack of ankle socks have an athletic lightweight feel. With fully synthetic fibers: 80% Polyester 17% Nylon 3% Spandex - you’ll get the performance materials out of these socks with the all day comfort you’re also looking for. So if your job requires you standing on your feet - or fun needs to kick up the athletic factor - we have you covered. Ribbed arch support. Mesh top panel - for extra breathability. Synthetic fibers that will increase the endurance of your sock for many washes to come and also not break down as quickly. Additionally the man-made-fiber nature of our socks - allows for extra warmth on the cold days and quicker drying nylon fibers for the hot (or strenuous activity days). The height hits right above the ankle on most ladies. I wear a size nine shoe and these fit well for me (not too tight). The model is around a size 6 shoe and she doesn’t think they are too big. Our office gals like to wear these during the day and take them hiking on the weekend. Transition easily from work to play with these athletic ankle socks.
