The Scan Angle specifies the alignment of the foot in the frontal plane relative to a provided reference position and is specified in degrees.

A positive value indicates an inversion of the 3D foot scan relative to its reference position.

• Increasing the inversion angle will increase medial arch height, medial heel wedging and total medial support of the orthosis.

A negative value indicates an eversion of the 3D foot scan relative to its reference position.

• Increasing the eversion angle will increase lateral arch height, lateral heel wedging and total lateral support of the orthosis.
