An electrodynographic study of foot function in shoes of varying heel heights.

Forty-three female test subjects had electrodynographic gait analysis performed in barefoot, low-heel shoe, and high-heel shoe conditions. Comparisons of segmental foot function, actual pressures, and pressure durations were determined. The findings suggest that an increased duration of forefoot loading, rather than an increased actual pressure, is responsible for pedal pathology secondary to wearing high-heel shoes. Contrary to previous reports in the literature, evidence of abnormal pronation in high heels was not found in this study.
