The Impact of Non-Athletic, Flat-Soled Sneakers on Gait Kinematics: A Comparative Analysis with Socks
DescriptionThis study investigates the kinematic effects of non-athletic, flat-soled sneakers on lower extremity joints (hip, knee, and ankle) during walking. Ten healthy gym-goers (24.4 ± 1.7 years) underwent treadmill gait analysis under two conditions: walking in non-athletic, flat-soled sneakers and walking with only socks. Gait kinematics were captured using the Gait Real-time Analysis and Interactive Lab (GRAIL) to assess osteokinematic changes and gait parameters. The dependent variables included cadence, initial double support time, single support time, stride length, terminal double support time, and total double support time. Results indicated that walking with socks significantly increased cadence (p < 0.0001) compared to shoes. Additionally, initial double support time (p = 0.018), terminal double support time (p = 0.0056), and total double support time (p = 0.0092) were significantly lower in the sock condition, while single support time was significantly higher (p = 0.0103). No significant difference in stride length was observed between conditions. These findings suggest that wearing non-athletic, flat-soled sneakers may negatively impact proprioception and balance compared to walking barefoot in socks. Further research is warranted to explore the influence of different footwear types on gait biomechanics and postural stability.
