AbstractTo address the conflict between occupational safety protection and biomechanical adaptability in safety shoes，this study investigated the influence of shoe collar height on lower limb joint kinematics based on biomechanical principles，aiming to optimize protective footwear design. Eight young male participants were recruited，and a 3D motion capture system was used to quantitatively analyze lower limb joint dynamics while wearing low-cut safety shoes，high-cut safety shoes，and regular sports shoes at walking speeds of 3.5km/h and 5.6km/h . Key findings show that：（1） High-cut safety shoes significantly restricted ankle range of motion （ROM），when wearing high-cut safety shoes，the maximum ankle angles in the sagittal and frontal planes were reduced by approximately 4～7∘ and 5∘～6∘ respectively compared to wearing low-cut safety shoes.（2） Low-cut safety shoes maintained ankle ROM close to that of regular sports shoes （difference <12% ） while reducing compensatory knee joint movements.（3） When walking speed increased to 5.6km/h ，the restrictive effect of high-cut shoes weakened but remained significantly greater than that of low-cut shoes.The study confirms that safety shoe collar height significantly affects joint mobility across different walking speeds. Low-cut designs can optimize biomechanical performance while maintaining protective functionality， providing quantitative evidence for ergonomic safety shoe selection and design in occupational settings.
