The prints of the human subtalar articulation are studied in several positions. An original set allows the fixation of the articulation under the pressure and in the desired position. Contactless areas of articular surfaces were colored by safranin O. In inversion and eversion the rate of incongruency of articular surfaces increased, while the contact was maximal in a mid-position, fixed by a passive blocking of the articulation. The support is the main position transmitting the pressures during the gait when the talocrural joint is in motion; the inversion is the essential movement when the foot is not in contact with the ground.
