Pronation is often discussed as something to correct. In this video, Dr. Ray McClanahan first describes it as a normal part of standing, walking and running, then explains what he considers problematic or persistent movement.
He uses a foot model and a standing demonstration to compare arch movement with different big-toe positions. A shoe and toe spacers help illustrate his view of the relationship between footwear, toe alignment and the arch.
The demonstration introduces the presenter's framework for thinking about foot posture. It is not a validated at-home diagnosis of overpronation, and the visible comparison does not guarantee that a shoe change or toe spacer will correct an individual's symptoms.
