Apparently this is why phil - It's extremely unlikely that they're coming from the outside," he said.
Grimm said the six feet, all encased in buoyant sneakers, have either come from the strait or the Fraser River, which empties into the strait.
The major ocean current off B.C.'s coast travels in a large counter-clockwise loop, he explained. Constantly changing local weather systems and tides usher floating debris caught in the current to shores in North America and Asia, rarely piling ocean rubbish in the same place, he said.
That may be why feet aren't piling up in other regions.
"It's very bizarre," he added.
However, another expert noted that when a foot separates as a body decomposes, modern running shoes could keep it afloat for large distances.
Curtis Ebbesmeyer, a U.S. authority on ocean currents and drifting objects, said a disarticulated foot could float for up to 1,600 kilometres in a buoyant sneaker.
