These Classic Men's Dress Socks come in a three pack and have a narrow rib. They come up to a standard men's sock length on the leg. They have a thin feel to them, not a thick sport sock feel. The Memoi Men's 3 pack is a similar option and more popular however, the Memoi run longer on the leg than the Classic and are better for a taller person. The 13-15 size of the Classic socks are about 9 inches from the heel to the toe. 80% cotton, 15% nylon, and 5% spandex.
