Diagrammatic representation of the sagittal-plane intersegmental orientation in double-leg support static posture (left), and at push-off (right) for the normally-developed (top) and plano-valgus feet (bottom). Calcaneus, midfoot, metatarsus and hallux segments were oriented according to the inter-participant average foot joint rotations recorded in the static acquisition (see Fig. 2) and at push-off (around 60% of the gait cycle; Fig. 3). Please note that the talus could not be tracked by the present foot protocol, and is only shown to improve image interpretation
