| Abstract: | Plantar pressure distribution of the designed cushioned soles was studied and compared with that of the commercially available sport shoes. A three-dimensional motion measurement system was used to obtain the peak plantar force, the peak plantar pressure, force-time integrals and pressure-time integrals, and one-way analysis of variance was used to analyze the performance of the designed cushioned shoes. The results revealed that in normal walking and jogging states, compared with the commercially available sport shoes, the peak plantar pressure in the heel region decreased by 13.65% and 6.05%, respectively. The peak plantar force decreased by 15.98% and 15.32%, respectively. The force-time integral decreased by 4.36% and 6.83%, respectively, and the pressure-time integral decreased by 10.58% and 11.00%, respectively. In conclusion, the cushioning performance of shoes is related to the exercise mode. For normal walking, the designed cushioned soles absorbed greater impact in the heel region, which was effectively cushioned, whereas in the jogging state, the designed cushioned soles exhibited a favorable cushioning effect in the forefoot region. The designed cushioned soles exhibited cushioning performance through the coupling design of material and structure, which effectively reduced impact force when landing and could optimize plantar pressure distribution. |
