They are assuming that they are suicides and the feet came of in the natural course of the body disintegrating.

The foot then floated to the surface because the shoe is light and ended up being taken by the currents to where they found it.

I will be the first to admit there are a LOT of assumptions in the statement but that is their current working theory.

Funny how they ALL land in British Columbia!

I think they are also suicides, but I’m going to go out on a limb and say there is a space-time vortex underneath the Golden Gate bridge. When someone hits it just right, they are torn apart, with the feet getting teleported to British Columbia and the rest of them getting teleported to a big mound of body parts located in a crater on the dark side of the moon.

Seems odd that suicides would all prefer athletic shoes (one exception).
