Abstract
The angular relation of a Sach foot to a shin may be adjusted during assembly to provide a desired heel height so that one type of Sach foot may be stocked for each shoe size and adapted for different heights of heel. The connecting bolt passes through a rotatable trunnion transverse to the length of the foot and is pivotable between fore and aft limits, and material is removed from the confronting surfaces of the foot and shin during fitting or packing material is inserted between them to effect such angular displacement.
