HOW: In a standing position with all your weight on your unaffected side, gentle place your affected foot on the ground with the big toe pointed forward. Try your best to stretch the big toe and drive your heel backward. This stretch may not be comfortable. It is up to you to determine how much weight to put on your back foot - only put as much as you can handle. Go gentle!
FEEL: You should feel a deep stretch in your big toe itself, and potentially under the big toe/arch as well.
COMPENSATION: None. Only put as much weight as you can handle. This joint is a sensitive one, go slow!
