Foot morphology development with age.

We studied the podogram from both feet in 1676 school-children of both sexes (663 boys and 1013 girls), aged between 3 and 17 a using 3 footprint measures (footprint angle: Clarke [1933]; footprint index of Chippaux [1947] and Smirak [1960]; arch index [Staheli et al. 1987]) and found clear differences according to age. Our findings showed a tendency in both sexes in early childhood to present a low internal arch until the age of 5 and 6a.
