The measured ankle hangs over the edge of the chair. (Figure 2). (2) The Subtalar Joint Alignment (neutral position). The participant keeps the captured foot neutral to make the transverse and longitudinal arches visible.  Both legs (dexter/sinister) were digitized similarly (Figure 2). Creating a 3D foot model (Figure 2):data optimization in Artec Studio 14. (1) Used software algorithms: Model creation (scan quality), Auto-Alignment,
