When Annabella learns her slave's addiction to her feet, she learned the source of her power. She knows that he will do anything to get to her feet. When he leaves to go on a business trip, she makes a video of herself. She sits on a chair and props up her boot clad feet. She takes her boots off and reveal her nylon clad feet. She knows that seeing her feet so close will drive him insane. As she flexes her feet, she knows he is masturbating and fantasizing.
