UGG boots, a flat footwear with minimal medial arch support, have become one of the top footwear choices today, particularly for women. The lack of plantar foot support may cause foot injury due to over pronation in the subtalar joint. Therefore, the purpose of this study was to examine the kinematics of barefoot and minimal foot support boot walking. Ten female subjects walked on the treadmill barefoot and in MFS boots. The results showed no statistically significant difference in the kinematics of lower limb and subtalar joints between the conditions. This study suggests that MFS boots do not limit rear foot motion. It may be due to the participants in the study having low pronation ankle profiles and the short duration of MFS boot wear. Future study is warranted to examine the long term effect of wearing MFS boots with various ankle pronation profiles.
