Biomechanical effects of insole material stiffness on the human foot: a finite element analysis.

ABSTRACT: Functional insoles are widely used to redistribute plantar pressure and support the medial arch; however, the biomechanical effects of insole material stiffness remain unclear. This study employed finite element analysis (FEA) to investigate the relationship between insole stiffness and foot tissue loading, providing a theoretical basis for personalized insole design and clinical application. A three-dimensional finite element model of a healthy 26‑year‑old male foot and insole was reconstructed from CT images. Exploring the trend of the insole material stiffness on foot biomechanics through parametric analysis. Six insole materials with elastic moduli of 100, 260, 1,000, 3,000, 5,000, and 500,000 MPa-were analyzed, The Poisson's ratio for all insole materials was assumed to be 0.45. Two l
