Changes in foot shape during long-distance running may lead to alteration in shoe fit. However, little information is available on changes in foot shape following long-distance running. The purpose of this study was to assess changes in foot shape in experienced runners after a single long-distance run. Data from the right feet of 21 subjects were obtained using a foot scanner before and after running 35 km on an asphalt road. After the run, the dorsal height, navicular height, and arch height ratio were significantly decreased. Midfoot cross-sectional shape after the run was deformed laterally compared to before running. Lateral deformity of the lateral dorsum was seen in 76.2% of the feet. For the medial side, 47.6% of feet deformed medially and 38.1% of feet did not change. The findings of the present study suggest that foot shape is altered during a single long-distance run. These results suggest that footwear fit and comfort could be affected during long distance running because athletes tie their shoelaces based on their pre-running foot shape. View Full-Text
