[单项选择]
Why would any woman in her fight mind choose to walk on the balls of her feet with her heels propped up by spikes The historical answer is that high heels reflect aristocratic tastes-specifically, the tastes of the seventeenth-century French court, which first popularized them in Europe. Not only did heels keep the wearer’s feet relatively mud free, they also created a physical elevation to match the social elevation of the stylish, exaggerated the strutting gait of the noble classes, and they suggested, by their very precariousness, that their owners could afford not to worry about falling on their faces. Indeed, as Bernard Rudofsky points out, seventeenth-century wearers of high heels, men and women, frequently had to be transported in sedan chairs because they could not manage cobblestones on foot. Some "heels" in that era were actually full-soled platforms, and to walk on these things at all, one needed the constant elbow support of two Servants.
