RFLat: lateral rearfoot; RFMed: medial rearfoot; MFLat: lateral midfoot; MFMed: medial midfoot; FFLat: lateral forefoot; FFCt: central forefoot; MFMed: medial forefoot; GToe: great toe; CI95%: 95% confidence interval. &: as the midfoot region was loaded only in ≅5% of the trials, the percentage difference and ICC were not calculated for this region.
