Abstract
To overcome the expense and limitations of cadaveric testing, we developed a finite element (FE) foot model. Previous foot models have included hyperelastic materials, plantar fascia, and extrinsic muscle forces [1]. We also included the plantar fat pad and both distal and proximal cartilage in our model. We validated the model by comparing plantar pressures and joint angles to literature sources and cadaveric testing data.

We validated the model by comparing plantar pressures and joint angles to literature sources and cadaveric testing data
The model includes: foot bones, distal and proximal cartilage of selected joints, plantar fat, with the remaining volume inside the outer skin boundary defined as a general soft tissue (Figure 1)
