Jaws - Sneaker for a Dead Man.
Perhaps one-third into the movie, a young man in a very small boat rows over near some young kids and tries to tell them how to tie a knot. The shark soon appears and knocks over both boats. Watch closely and you will see that the young man is barefoot when he falls out of the boat. But after the shark bites him, his leg sinks to the bottom with a sneaker on it.
