How can a dancer’s pad lead to plantar plate sprain?

I just got a great question from a runner who had been using a thing called a dancer's pad. A dancer's pad is sometimes used to help an injury to these little bones under the big toe joint called the "sesamoid bones." If one of the sesamoids is painful and irritated and you're trying to take the pressure off of it, an easy way to do that is to place a dancer's pad in your shoe. How can a dancer's pad lead to a plantar plate sprain? Well, that's what we're talking about today on the Doc On The Run Podcast.
