Personally I'd vote for the foul play scenario, since crabs and other ocean scavengers don't differentiate between right or left and it's too much of a coincidence to have 4, sneaker wearing, right feet found with no other body parts.
In the last couple of years there has been a large number of missing persons who have never been accounted for, so, hopefully these feet don't belong to them.
If were lucky, the DNA testing will solve the mystery and it'll just have been the biggest coincidence in BC history.
