Any orifice it can fit into, it can also come out of before being detonated, and anything with a volume enough to hide in a normal-sized shoe will have a total volume small enough to be stuffed up a rectum.
OTOH, I guess doing the "I've gotta go to the bathroom" dance while in line for the checkpoint is going to be about equally suspicious as doing it in customs.
