In recent years, the number of patient of locomotive syndrome has been increasing due to advancement of aging society. Knee osteoarthritis is one of those pain. In order to prevent this symptom, we develop shoes sole fitting to personal walk characteristics. In this research, we measured the sole pressure of a subject by using the measurement apparatus by which three dimensional ground reaction force can be measured. We examined the characteristic of the right foot of a man of the 23 years-old physically unimpaired person. The shoe sole pattern areas was designed by following aspects; (1) At the heel area, the vertical reaction force was concentrated at the central part rear of the heel area and the horizontal reaction force was observed highly at the front of the heel area. Therefore, we design the sole pattern by embedding a shock absorbent material into the central part of the rear heel area and an abrasion-resistant material into the rear heel area. (2) The horizontal reaction force varies direction back and forth at rear of MP joint in the toe area. For the design of the sole pattern, an abrasion-resistant material is put into this area. (3) The vertical reaction force was concentrated near the second finger. Therefore, we design the sole pattern by embedding the material with high bending rigidity into the whole area of the toe. The effect of designed shoe sole on the change of personal walk characteristics was discussed from the experiments.
