Nowadays, high heels are gendered footwear; they are culturally associated with women or femininity. But this is not for whom high-heeled shoes were made for in the past.
Historically, high-heeled shoes were men’s footwear, worn by men in horseback-riding cultures, where heels helped them stay in the stirrup (e.g. Persian shoes in 9th century, vaquero boots in 16th century or cowboy boots in 19th century). High-heeled shoes were important for their functionality and practicality, two of the most traditional masculine traits when it comes to footwear.
