I've cut some thin bare , electronics circuit board, the front half of
insoles in shape, to place under the built-in insoles.
Stiff and light but thin glass reinforced polyseter sheet, may stop the

The steel shank is there so that, when you retire after a working life
wearing such boots and walking on concrete factory floors for 8 hours
per day, your feet are in such a bad shape that you walk in a kind of
shuffle motion, keeping pressure off the sole as much as possible.
