When can I walk barefoot at home with a 2nd metatarsal stress fracture?

I was talking with an injured runner who had a stress fracture in the second metatarsal bone. He was working hard to get it to heal faster. He had gone through the stress fracture course for runners, and he was doing great. He asked me a question: When can I walk at home barefoot with a second metatarsal stress fracture?  Well, that is a great question and that is what we're talking about today on the Doc On The Run Podcast.
