Running shoes float. Corpses (after a period of time) sink. Little sea creatures and decomposition eventually detach the extremities from the body, but the shoe protects the foot itself. The shoe floats to the surface with the foot inside and drifts around until it lands somewhere.
You could probably look at the tides and currents in the area and figure out where they are coming from. Could be boaters or deckhands on commercial vessels, or folks falling in from bridges or shores, or suicides. Locals would be reported missing, but not necessarily people from commercial vessels.
Who's feet? From where?
This has got to be the worst guerrilla advertising campaign by Nike that I've ever heard of. jk
I’d say there’s a common M.O.
If they were accidents or suicides the whole bloated corpse would wash up. These deaders have been cursorily weighted down so that the sneaker-shod foot doesn’t float free until the body rots sufficiently.
Yours is probably the most likely explanation, but then, why don’t we see feet washing ashore in waterways all over the world? Is there something special about the geography of this area that causes the feet to say, swirl around and eventually wash up, instead of being carried out to sea? Or are the BC’ers just the only people on the planet who think finding a string of floating, detached feet is actually news?
Except maybe off of the coast of East Africa, people don’t just fall off of ships. LOL!
