Goddess Sheila was so cold, and the weather outside was not good for her either, but this guy made fun of her heavy jacket, and she tried to block him, but it was impossible, and she decided to shut him up because his mouth was runny like a girl's. She filled his mouth with her boots and made him lick them clean until she knew he had enough is when she let him go
Goddess Sheila wanted to get info from this guy and that is why she opted to use her boots to do it. The mistress had the guy lick her boots in order to avoid her trampling and dominating him for the sake of it and to send a message. She wanted to get the info so when he delayed to give it to her, he had to lick her soles.
Mistress Vanny caught this guy trying to steal her expensive boots and she punished him for it. She did not want to encourage his behavior and he had to learn to make an honest living. She knew that her expensive boots had a ready market out there but he was not lucky today because she used the same boots to torture and humiliate him. He had to lick them and especially the soles which were dirty.
