Ozone socks came into my life because I couldn't find any socks for myself that would stay up. The bonus is they are comfortable and stylish in a wide range of fun colors and patterns. Of course, I can't buy just one of anything, so I bought enough to share with you, too! These mostly cotton socks fit shoe sizes 5-11. They are 84 percent cotton with just enough nylon and spandex to make sure they stay up.
