Last, for mass production of orthopedic shoes, has a spacer to set the vertical gap between the stiff upper and lower bodies at the foot section

摘要

The shoe last (10) has a foot section (12) with a stiff upper body (20) and a separate stiff lower body (22). An adjustable spacer (24), as a pneumatic cushion, adjusts the vertical gap between the upper and lower bodies. The spacer can take up at least three different gaps and can have an infinitely variable action.
