There are many study to measure shoe motion as foot motion. However, these may not measure exact foot motion. It is known that insole formed pressure sensors are useful to measure in-shoe foot dynamics, but relationship between in-shoe foot kinematics and plantar pressure is unclear. The aim of this study was to examine relationship between in-shoe foot kinematics by using multi-segment foot model defined by jig-attached cluster markers and plantar pressure. Two males were recruited for this study. Foot kinematic variables and plantar pressures collected during static, walking and running inserting a foot arch support insole in shoe were compared to not inserting insole condition. Foot arch support insole reduced plantar pressure acting in medial part of foot bottom and pronation angle of each segment during static stand position in each subject. Moreover that insole reduced pronation angle of rearfoot in subject A during walking and running. Nevertheless, there were not so much change between subjects for hallux plantarflexion angle during walking and running, plantar forces were changed. In conclusion, this study suggests that there is relationship between in-shoe foot kinematics by using multi-segment foot model defined by jig-attached cluster markers and plantar pressure.
