Bobby sox are a type of women's socks that stretch up to or over the ankle and are worn with saddle shoes. Common synonyms for bobby sox include ankle socks, crew socks, and quarter socks. These socks were very popular in the 1940s and 1950s among teenage girls, especially those who loved dancing and rock and roll music. Some slang terms used to refer to bobby sox include "roll-up socks," "pedal pushers," and "ankle-sock garters." These accessories may seem like a thing of the past, but they're still worn by many people today as part of retro fashion or as a nod to an iconic era in American cultural history.
