This mistress had bought new high heels when this loser pissed her off. She was still wearing them and she saw no need to remove them. She trampled him with the same heels to make him learn his lesson. She wanted him to learn and realize that he was supposed to do what she said and not do his own things. The pain he felt as she hard trampled him sent the message home.
Mysteria loves to inflict pain. The best way she knows how is by trampling slaves with her full weight
