Sophie's boots are one of the hardest footwear she has ever stood on her slave with and they are her own personal boots, her boots are very thick platform hard plastic soles and she is trampling all over her slaves hands and fingers with them she uses both her heels and the ball of her foot to step all over his hands and fingers she tramples all over the tops of his hands and also the palms of his hands, this girl is really hurting him and clearly does not care you even see his fingers turning purple and white.
