Effects of Diabetic Sole Design with Auxetic Structure on Reducing Plantar Peak Pressure

Abstract: By 2035, the global prevalence of diabetes is estimated to reach 532 million. Foot ulcers, as a complication of diabetes, are particularly important to prevent in diabetic patients by regulating plantar pressure. Inspired by the mechanical properties of auxetic materials, a auxetic diabetic shoe was designed. The study utilized finite element analysis to compare the mechanical properties of the 3D auxetic lattice midsole with the traditional hexagonal lattice midsole, including peak pressure, peak displacement, stress energy, and viscous energy dissipation. The analysis of the mechanical properties of the auxetic structure provides valuable insights for the design of diabetic footwear soles.
