How do cushy running shoes cause stress fractures?

If you have a high arched foot that is prone to getting stress fractures, a podiatrist may have told you that you need cushy running shoes. I got a question from someone who was given that advice. She said, “I am so confused, I thought stress fractures were from pounding. I got a stress fracture, and my doc said it was my cushy shoes. I do not understand how this is true.” How do cushy running shoes cause stress fractures in the foot?  Well, that is a great question and that is what we're talking about today on the Doc On The Run Podcast.
