We used geometric morphometrics for a detailed analysis of footprint shape in a sample of adult women. The outline of the footprint, including the toes, was represented by a comprehensive set of landmarks and semilandmarks. The first four principal components represented the major axes of variation in foot morphology: low-arched versus high-arched feet, long and narrow versus short and wide feet, the relative length of the hallux, and the relative length of the forefoot. These shape features varied relatively continuously across the measured individuals without any distinct clusters or discrete types of footprint shape. We identified and visualized influences of body mass index (BMI), shoe size, and the frequency of wearing high heels on footprint shape. We further assessed average and individual asymmetry in footprint shape.
