I bought these nice sandals on my last vacation. They've a chunky heel and hard soles - with a pretty unique tread. And of course, since they're new, all the edges are still extremely sharp as well :-D I drive the slave into the living room on all fours and then make him lie down - so I can try trampling him with my new sandals. They leave nice marks all over his chest and stomach - I think I'll use them for trampling more often :-D
