The study shows that the average male participants' feet are longer than that of the female participants' feet, while the female feet are relatively narrower but higher than those of the male participants.
Accurate, consistent measurement of foot-ankle geometry is essential for the design and manufacture of well-fitting, functional, comfortable footwear; for the diagnosis of certain biomechanical disorders; and for consistent longitudinal monitoring and assessment of pedorthic treatment outcomes. We sought to formulate a basic set of measures characterizing the principal geometric dimensions of the foot, to investigate how these measures vary with increasing weightbearing, and to explore the implications of weightbearing changes in pedal geometry for orthopedic footwear design and manufacture. The right feet of 40 healthy men aged 22 to 71 years were scanned using the Department of Veterans Affairs Pedorthics Optical Digitizer in neutral alignment, sequentially bearing 0%, 10%, 25%, 50%, and 100% of the subjects' body weight. With support of the full body weight, the following mean changes in the pedal parameters were observed: heel-to-toe length, 1.5%; ball width, 4.3%; maximum heel width, 4.8%; and instep height, -9.3%. On average, 71% of the changes sustained in the pedal parameters at full weightbearing occurred when, or before, 25% of the body weight was applied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
