In sports, there is a constant discussion about the hyper-pronation and supination of the foot during loading and its relation to injuries or dis-comfort. The purpose of the present study was to investigate the possi-ble differences in the subtalar joint in the midstance phase of running, between individuals with Pes Planus and Pes Cavus, after 5 min and 45 min of running. Thirty-four subjects, meeting the requirements for Pes Planus (30 feet) and Pes Cavus (35 feet), according to the criteria for Medial Longitudinal Arch-angle, were included in the study. The calca-neal vertical angle, representing the eversion/inversion of the subtalar joint, was measured using with two-dimensional digital analysis and Dartfish Software with the subjects running barefoot on a treadmill, be-fore and after 45 min of outside running wearing shoes. Both individuals with Pes Cavus and Pes Planus showed a significant increase in the calcaneal eversion (P<0.05) after 45 min of running. Between the groups, there was a significantly greater eversion of the Pes Planus, on the right foot, after 45 min of running (P<0.05) compared to the Pes Ca-vus. The effect of fatigue evident in the present study suggests that fur-ther biomechanical research should be considered when exposing the foot to the repetitive nature of running, conditions most likely responsi-ble for the overrepresented overuse injuries among runners.
