I have feet like yours ncrsbug.

I've been wearing custom orthotics past 15 years. It works for me.

I'm not totally convinced for me it's hereditary because my 5 siblings don't have feet like mine,..ie. with hammer toes, etc. None of my sisters wear narrow shoes and high arch stiletto heels. I know them....

Honest, some of it is due to improperly fitted shoes earlier in life..for me. That's my opinion. i know my parents made a conscious effort to buy shoes for the younger ones that were wide enough for fit around the toe box.
