Experimental Study of Evaluating Bio-Mechanical Characteristics of Cushioning System Using Nano-Shock Absorption Pocket
This study developed and evaluated a shoe cushioning system to reduce impact force patterns during running. The shoe cushioning system is composed with a polyurethane pocket, which contains water and porous grains to absorb the force against the weight inside the pocket. Load-displacement curves for the shoe cushioning system were obtained from an instrumented testing machine and the results were compared with various pockets that have air, water or grains. Mechanical testing showed that the pocket with 5 g particles was the best for the shoe cushioning system. This founding will be helpful to designing the shoe.
