Go-go boot
Go-go boots are a low-heeled style of women's fashion boot first introduced in the mid-1960s. The original go-go boots, as defined by André Courrèges in 1964, were white, low-heeled, and mid-calf in height, a specific style which is sometimes called the Courrèges boot. Since then, the term go-go boot has come to include the knee-high, square-toed boots with block heels that were very popular in the 1960s and 1970s; as well as a number of variations including kitten heeled versions and colours other than white.
