This paper is an attempt to complete previous works on this topic, especially Schultz, by new measurements and indices. From the calculated indices, listed at the end in a table, graphics are drawn and related to four main contents: (1) relative length of the foot to the hind limb and its segments; (2) relative length of the different foot segments to the foot length and between them; (3) relative length of the first toe, or hallux, to the foot, tarsus and longest external toe lengths; (4) position of the morphological axis of the toes: here we define the notion of axony. In conclusion, we try to answer the following questions: (1) what are the mensural distinctions of the human foot? (2) are foot ratios suitable to establish a satisfactory morphological classification of the locomotory adaptations in primates?
