Wikipedia
Pedal pushers are calf-length trousers that were popular during the 1950s and the early 1960s. Often cuffed and worn tight to the skin, they are related in style to capri pants, and are sometimes referred to as "clam diggers". The name "pedal pushers" originated from the style originally worn by cyclists, because long pants can catch in bicycle chains, but the style quickly became identified with teenage girls.
