This study introduces a new biomechanical analysis for shoe insert materials, revealing significant differences in rigidity and energy absorption based on material type, thickness, and frequency. Proper material selection is crucial for effective pressure distribution and joint disease prevention.

Area of Science:

  • Biomechanics
  • Materials Science
  • Orthopedics

Background:

  • Degenerative joint diseases require effective treatment and prevention strategies.
  • Shoe inserts play a crucial role in managing foot biomechanics and alleviating joint stress.
  • Existing material analysis methods may not fully capture real-world performance under dynamic loading.

Purpose of the Study:

  • To present a novel methodology for biomechanical analysis of shoe insert materials.
  • To evaluate the rigidity and energy absorption characteristics of viscoelastic materials under dynamic conditions.
  • To investigate the influence of material type, thickness, and frequency on performance for treating joint diseases.

Main Methods:

  • Development of a dynamic testing machine to simulate real-world loads on shoe insert materials.

  • Determination of material loads in actual use scenarios.
  • Investigation of rigidity and energy absorption as functions of frequency and material thickness.

    • Main Results:

    • Significant differences in material behavior were observed based on type, thickness, and frequency.
    • Poron materials exhibited low rigidity, optimal for pressure distribution.
    • Noene demonstrated superior energy absorption capabilities.
    • Sorbothane's performance was highly dependent on thickness to prevent material flattening.

    Conclusions:

    • The proposed methodology provides a robust framework for evaluating shoe insert materials.
    • Material selection is critical for optimizing pressure distribution and energy absorption in shoe inserts.
    • Specific materials like Poron, Noene, and Sorbothane offer distinct biomechanical advantages for managing degenerative joint diseases.
