This study used Fifty Flat-Footed Person (FF, arch height 1.57±0.37cm，55.6±8.69㎏) and fifty Normal-Footed Person (NF, arch height 2.76±0.17cm，54.3±6.2㎏) as subjects. The foot kinetics and rearfoot motion in both walking (1.33m/s) and running (2.66m/s) were measured by EMED-Pedar System and PEAK analysis system. All the data were analyzed by one-way ANOVA（α=0.05）, The results were as fellow：1) In walking, the foot kinetics of FF’s midfoot area was several times larger than the NF. The FF’s rearfoot motion was larger than the NF. 2)In running, in metatarsal region and forefoot the FF pressure would move to outside whereas the NF move to inside. 3) In both walking and running, the midfoot area were different significantly in different velocity, but no difference for the rearfoot motion. The FF in easier to get fatigued and pain because of their gait unstable.4)In both walking and running, the rearfoot motion of NF was diffeent.
