there is something quite wrong with your comparison between feet and "bottoms"
we were NOT designed to sit. Sitting is something quite modern, we started sitting when chairs were invented. (And bicycles) People have walked for millions of years without shoes. People are now running without shoes.
so that comparison of feet and all the delicate structures that must rest upon a abike saddle doesn't quite work for me, sorry. good luck on finding a saddle. You were not able to explain why the Brooks does not work although I notice both saddles you tried were narrow.
good luck on your search i know it's not easy
