Feet

She never looks up when she walks, preferring to watch shoes and feet to faces and eyes. For her, feet have more character. They carry the weight of an entire being, showing strenth and resilience.
She loves the feeling of being surprised when she doesn't quite equate the shoes with the person - like the princess in her Chucks, the debutant with her vandalized toes, the genius with his canvas loafers, the Prince in his leather shoes and the firecracker in her flip flops.

If you want to know a person, truly know a person, look at their feet.
