"if the high heel is an accessory of female power—and if the definition of female power is sexual—that power has a very short shelf life. Is a 90-year-old woman in spike heels powerful or silly? Is a 12-year-old girl in spike heels powerful or inappropriate? So at what point is a woman allowed to be powerful? If her power is based simply on her sexuality, then that’s a very limited amount of time that women are permitted to be powerful."
