Recently, in the cold regions, pedestrians slips and falls in the freezing road surface. Then there are problems that they injured by that. To overcome these conditions, it thought that effective Anti-slip performance could be made by deciding the proper arrangement of Anti-slip material, from the measurement data of floor reaction force and pressure distribution of the shoe sole in a walk. So, anti-slip shoes were manufactured to a certain testee. And, anti-slip material used a glass fiber. When the improvement of Anti-slip performance was examined with three kinds of ways of examining. Though the base shoes were a frictional coefficient μ=0.08, sense value S=1.25 and an acceleration ratio Ra=0.151 respectively, the shoes manufactured by this system became μ=0.28, S=4.00 and Ra=0.235, and it was improved each 250%, 220%, 55.6%.
