feminizing the high heel through french erotica
It wasn't until the 18th century that heels became feminized. The history of this feminization can be traced back to French porn photographers, who realized that high heels made the butt look perkier in photographs. It wasn't until these images became widespread that the heel resurfaced, and only then did they become associated with femininity.
