Here's a couple of links to Survivor, in the first they have the muddy challenge, three girls in sneakers, but it gets hard to tell who's who. In the second, you have to just watch the beginning, there's a good shot of Parvati taking off her muddy Sauconys and shows her bare feet coming out of these really muddy shoes.
