ID:

Designation:

Arch area

Definition:

Area below the foot arch. It is calculated on the footprint as the area confined between the foot tangent line to the medial side of the foot and the foot arch. Footprint is obtained by cutting the foot by a plane parallel to ground at 1mm beyond the ground level.
