This is a case of internal tibial torsion. In particular, watch the right limb. We see a decreased progression angle of the feet, Right greater than the left, a “crossing over” gait; and bilateral toe off in supination, Right greater than the left. This can impair a persons ability to engage the lumbopelvic stabilizers adequately, impair patellofemoral tracking, and generate a host of compensatory motor patterns that are sub-optimal.

This individual’s shoe choice renders a degree of over-correction and is magnifying the problem to a degree.
