As an electrical engineer, I can sorta back up the exploding ankles. Even though I never heard of of something like that happening before. The body has higher electrical resistance in joints like elbows, knees and ankles, thus more electrical effect is exerted there (electric shock victims usually have internal(!) burn wounds in the elbow joints. Even if the rest of the arm seems okay). So if the current air-gapped from the ankles to the ground, because of, say rubber soles in the shoes. The result would be exploding ankles and intact shoes.
