Google “what happens to a dead body in the sea over a long period”, that might explain it to you. It was just fortunate that the shoe must have been tied on tightly and was of sufficient good quality to survive itself. And not be palatable to sea creatures. The other shoe might be out there too, as yet undiscovered.Surely they can asses the sneakered foot and decide how it was removed from her leg? i mean we can put a rocket into space and land a capsule on the Moon and we can't tell how she came to have a missing foot?
