Today's discussion actually comes from a question from a runner in the Monday, Wednesday, Friday Coaching Group.

This is a runner who has a condition called "hallux rigidus."

He wanted to understand the best way to assess your running shoes. He also wanted to know whether or not it was possible to identify hallux rigidus just by looking at the soles of a runner's running shoes. 

When you get hallux rigidus, your big toe doesn't actually "dorsiflex" or come up away from the ground enough to allow you to walk or run without doing something to compensate. That shift in the way you walk creates a characteristic wear pattern on the sole of the shoe. 

Today on the Doc On The Run Podcast, we're talking about running shoe wear patterns with hallux rigidus.
