Lamina pedis (calcaneopedal unit) according to MacConnail and Basmajian²². An example of the adaptability of the twisted lamina pedis illustrated by Seringe and Wicart (2013):⁹ supination (Sup) of the forefoot is compensated by an untwisting of the lamina pedis with subsequent valgus of the hindfoot. In order to maintain a plantigrade position of the foot and vice versa, pronation (Pro) of the forefoot is compensated by a varus of the hindfoot. This figure has been reproduced with permission.
