what is the fabric content of these socks? i like a soft cotton. i see another product of yours which is identified as microfiber, can you describe microfiber?

The A106 is made out of CoolMax 71% Nylon 25% Spandex 4%. Microfiber is a type of nylon that gives our socks a dressier look. It makes the garments cooler but not as thin as a sheer-looking sock and not as tickled as a cotton material; it is the perfect in-between.
