Its like saddles go try some in person ..
I still have Birkenstock 3/4 insoles they are cork composites no plastic stiffeners , like 'super feet'. or Spenco do.
The US importer of Birks quit bringing the Insoles in, so now you seek a German retailer to ship them
superfeet, spenco , go shopping.. the stiff arch support is the part that helps..
