Leather flats, make girls feet stink the worst.
If they are new, they smell like leather or whatever they are made of. After they are worn, they smell like feet. Usually girls wearing high heels/flats on bare feet smell bad because they aren't wearing any socks nor nylons.
first of all, that is really really disgusting. second, NO. girls are pretty insecure enough let alone someone smell her SHOES! good lord.
Suede flats/heels smell very stinky (especially on bare feet) because the shoes keep the feet warm and they sweat.

Tell her it's part of a science project.

Platts
They small better with correct personal hygiene.
Girls and boys ejaculation both smell, it is normal.
It is inappropriate and disrespectful to ask someone to smell their shoes without their consent. Respect their personal boundaries and ask for permission before making any such requests.
