The Frank Lloyd Wright Saguaro Women's Socks - Black design is adapted from one of Wright's most popular designs. In 1926-27 Liberty Magazine commissioned Frank Lloyd Wright to design a series of cover designs that the editors thought to be too "radical" and never used. Why not architectural fun for the feet? Content: 80% Cotton/19% Nylon/1% Spandex. Our women's sock translates to a 5 - 10 women's shoe.
