Madame Marissa needed to find a way to dominate this guy and have him cry. That is exactly what she did to the guy and she used her hiking boots to do it. The mistress felt that the best thing to do to him was to use crush him and she even went ahead to do it with the help of her friend. They crushed every inch of his body.
Madame Marissa did not like how her hiking partner was behaving. He was slowing her down and making it harder for them to continue hiking. She had to complete the hike and she did not like what he did. That is why she chose torture as well as degrade the guy with her hiking boots. He was crushed and trampled until he agreed to stop wasting her time and slowing her down.
Madame Marissa needed to use her hiking boots to hand trample this loser. He had shown disdain to her and she did not like that. She had to punish him and she had to torture him so that he learned to stop doing those things. It was more painful than the guy thought it would be and he cried at what she did. And that is how he learned his lesson.
