Abstract
An orthotic insert assembly having a stationary heel post with a guide slot and an unattached rigid plate member with a depending peg that is received in the slot. The peg cooperates with the guide slot to control and direct a medial-to-lateral rocking movement of the plate member as the wearer's foot progresses through the gait cycle. The slot may be angled to impose a predetermined direction on the rocking movement.
