What happens if I run before my broken toe heals?

I got a great question that actually came from one of the discussions I have with runners who are in the recovering runners coaching group. She had just broken her toe and could barely walk on it, but she was really worried that she was going to have to use a fracture walking boot for a month or month and a half. She wanted to know specifically when she could start running. Today on the Doc On The Run Podcast, we're talking about what happens if you run on a fractured big toe before it completely heals.
