The Athletic Socks for Men and Women are too small around the top of the socks and are hard to get on.. I received 10 pairs of black sock . They are made of 67% cotton 30% polyester 2% fiber and 1% rubber. The toe and heel are reinforced. These socks are comfortable once you get them on. They are soft, lightweight and durable. #RankBoosterReview ii, Sponsored iii, Athletic Socks for Men and Women https://www.amazon.com/gp/product/B074RF7367/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
