Left (a-d), mean temporal profiles of pairs of foot joints rotations (±1 standard deviation band) normalized to stance duration across all walking trials of all subjects. Right (a1-d1), angle-angle trajectories (i.e. coupling angle) for the pairs of joints rotations on the left. Where: ShCa (y) is the coronal-plane rotation of the midfoot with respect to the calcaneus; CaMi (x) and CaMi (y) are the sagittal and coronal-plane rotations of the midfoot with respect to the calcaneus; MiMe (y) is the coronal-plane rotation of the metatarsus with respect to the midfoot, and MeHa (x) is the sagittal plane rotation of the hallux with respect to the metatarsus. The trajectory initial point (0% stance) is highlighted by the ‘+’ symbol
