M.P.
Pot always smelled a bit like skunk to me. I smoked quite a bit when I was younger. If the kid did walk around a skunk, the smell wouldn't just be on his shoes. If the smell is a pot smell and it is only on the shoes, (likely only one shoe) I would suggest that is where he stashed the baggie. It is possible too though that someone else placed a baggie in his shoes to make them smell to get him in trouble. I know the story seems lame but if you were in a group of kids that accused you of smelling like or smoking weed, you would probably blame any smelly thing that you could think of. :)
