Designers and manufacturers like Salvatore Ferragamo, Roger Vivier, and Herman Delman reintroduced the raised sole to footwear fashion in the 1930s. Ferragamo designed these rainbow sandals in 1938, probably inspired by the flamboyant and colorful costumes often seen in American musicals. One year later, Judy Garland sang "Over the Rainbow" in the movie The Wizard of Oz, and since then, this famous design is often associated with her.
