This study aims to analyze the impact of different 3D printed biomimetic midsole structures on gait phase and gait ratio to optimize running shoe design. Participants wore shoes with various 3D printed midsoles while gait ratio(heel rotation, foot balance, forefoot balance, hallux stiffness, medial forefoot balance, and meta loading) and gait phase(forefoot off phase, foot flat phase, forefoot contact phase, and initial contact phase) data were collected using a gait analysis system. These metrics reflect foot pressure distribution, gait symmetry, and balance, providing insights into how midsole structures affect gait. The results showed that different 3D printed biomimetic midsoles significantly impacted gait phase and gait ratio. The 1TS structure, improved the stability of the stance phase and reduced swing phase imbalance, demonstrating its potential for optimizing gait balance and efficiency. This indicates that 3D printed biomimetic midsoles can notably influence running gait, with the 1TS structure enhancing stability and balance, offering a new direction for optimizing running shoe design to improve performance and comfort.
本研究旨在分析不同3D打印仿生中底结构对步态阶段和步态比例的影响，以优化跑鞋设计。参与者穿着带有各种3D打印中底的鞋子，同时使用步态分析系统收集步态比例（脚跟旋转、足部平衡、前脚掌平衡、拇趾刚度、前脚掌内侧平衡和跖骨负荷）和步态阶段（前脚掌离地阶段、足放平阶段、前脚掌接触阶段和初始接触阶段）数据。这些指标反映了足部压力分布、步态对称性和平衡，有助于深入了解中底结构如何影响步态。结果表明，不同的3D打印仿生中底对步态阶段和步态比例有显著影响。1TS结构提高了站立阶段的稳定性，减少了摆动阶段的不平衡，显示出其优化步态平衡和效率的潜力。这表明3D打印仿生中底可以显著影响跑步步态，1TS结构增强了稳定性和平衡，为优化跑鞋设计以提高性能和舒适度提供了新方向。
