This one of those conundrums in that as males, we value a little bit of height but our girl side wishes to shrink down a few inches. Alissa has that average girl stat, of being around 5' 6"/7" and I bet she gets her shoes from the standard GG racks too. (accompanied by my sneering look)
The problem for me is that I have Sasquatch feet and flats emphasize this feature. Heels at least take some of that flipper feet look away and give me a fighting chance of looking something akin to normal. A bag over my head helps a lot but draws as much attention as it deflects.
