“…Nevertheless, it was also clarified that exercising for a long-time while wearing inappropriate sports shoes would increase the odds of foot injuries. Plantar fasciitis, foot fractures, and heel pain were all found to be associated with abnormal plantar pressure concentration and overload during exercise, while the structure and material property of footwear play crucial roles in this process [ 5 , 6 , 7 , 8 ]. Thus, developing a comprehensive biomechanical approach to investigate the effects of shoe characteristics on plantar variables and the foot-shoe-ground interactions could not only help to promote the optimization of footwear product design but also prevent foot injuries.…”

Nowadays, footwear serves an essential role in improving athletic performance and decreasing the risk of unexpected injuries in sports games. Finite element (FE) modeling is a powerful tool to reveal the biomechanical interactions between foot and footwear, and establishing a coupled foot-shoe model is the prerequisite. The purpose of this pilot study was to develop and validate a 3D FE coupled model of the foot and sports shoe complex during balanced standing. All major foot and shoe structures were constructed based on the participant’s medical CT images, and 3D gait analysis was conducted to define the loading and boundary conditions. Sensitivity analysis was applied to determine the optimum material property for shoe sole. Both the plantar and shoe sole areas were further divided into four regions for model validation, and the Bland–Altman method was used for consistency analysis between methods. The simulated peak plantar and sole pressure distribution showed good consistency with experimental pressure data, and the prediction errors were all less than 10% during balanced standing with only two exceptions (medial and lateral forefoot regions). Meanwhile, the Bland–Altman analysis demonstrated a good agreement between the two approaches. The sensitivity analysis suggested that shoe sole with Young’s modulus of 2.739 MPa presented the greatest consistency with the measured data in our scenario. The established model could be used for investing the complex biomechanical interactions between the foot and sports shoe and optimizing footwear design, after it has been fully validated in the subsequent works under different conditions.
