足底圧分布に着目したインソールのフィット感に関する研究(シューズ(1))

Comfort is one of the most important factors for runners in choosing running shoes. However, it is difficult for runners to find comfortable shoes, because variation in the shoe size is limited. Morphological fit of the shoe can be improved by using insoles, because insoles can be easily customized. In order to improve the fit by this way, it is necessary to know the relationship between the shape of insoles and the perception of the fit. The purpose of this study is to investigate the relationship between the shape of insoles, pressure sensation, and pressure distribution during running. Subjects were 15 student athletes. 7 insoles conditions (control and 2 arch pad height in 3 different locations) were compared. The location of the arch pad was determined based on the location of navicular bone for each subject. Each subject evaluated the comfort by Visual Analog Scales. Foot pressure was measured by an F-scan system. Pressure sensation at the plantar arch was related to the contact area and pressure. The pressure sensation was different in 3 location of arch pad. The pressure sensation was related to the contact area when the arch pad is located anterior to the navicular bone, to contact area and pressure when it is located at the navicular bone, and to the pressure when it is located posterior to the navicular bone.
