The shoes not only protect the feet from decomposition, but also makes them buoyant — which is why the feet make it back relatively intact without the rest of the body.
The BC Coroners Service told BuzzFeed News it has been able to identify eight of the previous 12 feet, matching them to six individuals. No foul play is suspected in any of the cases.
The coroners are working with the police to try to find possible matches or links to missing persons cases for the latest foot.
Andy Watson, a spokesperson for the BC Coroners Service, said the investigation was still in its early stages, and that the investigation would try to identify the person, how they died, and whether it can be prevented in the future.
