12 Pairs of black women’s no-show socks - fully synthetic fibers - 80% Polyester 17% Nylon 3% Spandex. Kick up your low no show socks a notch with our fully synthetic fibers - which means less shrinkage and longer durability. Our medium size fits shoe sizes 6-9 best, but a size 10 has been known to rock these. Our lightweight thin liner type ultra no show is reinforced at the top with an elastic binding. So if you need them to slip into some dress flats or rock with your low tennis shoes - you’ll find the comfort of these synthetic socks. Because of their man-made-fiber materials our socks stay warmer than others and are quicker to dry on days when the heat gets to your feet. Additionally the fibers allow for more athletic uses - since there is no cotton in our socks - you won’t find the blistering you may be feeling with your current no-shows. Our 12 pack comes with 12 pairs of women’s cute and comfy no-show socks.
