Lisa:
Saw your note about foot volume confusion.
I am low volume. I have thin and bony long feet, normal to flat arches ... they tend not to be fussy. I wear flats easily, don't have trouble getting my feet into shoes, etc. Although ... over the last couple of years I have begun developing bunions which means pointy toes are getting harder to deal with (hence my decision to return those Zara booties). It's very easy for me to think about foot volume when I think about my sister-in-law's feet: hers are the direct opposite of mine, more compact, just have a blockier shape, more heft, and high arches. She needs more space in shoes than I do. I can tell just by looking at her feet and by looking at her shoe choices.
And here is the bible:
