Abstract
The purpose of this study is to investigate the effect of curving sole shoes to walking motion. The subjects were eight female university students (age: 19.3± 1.5 yrs, height: 159.3 ± 2.4cm, weight: 54.2 ± 4.3 kg). They walked about 6 meter on walk course with three kinds shoes and barefoot. The motion is simultaneously recorded by three High speed cameras (125fps) and two force platform. The results are as follows. The angle of ankle joint is decreased curving sole shoes compared with another two shoes. The phase of foot flat time of curving sole shoes is shorter than another. The kick phase became longer, and kick force became larger. The heel contact distance of curving sole shoes became near body. Curving sole shoes produced changes and trends in kinetic and kinematic characteristics that seemed to be advantageously for the walking motion.
