here is the answer to the original question:
Most of the girls that you see in porn are or were strippers. Those are the shoes of choice of strippers because they are comfortable, slutty and high... try walking an 8 hour stripping shift in uncomfortable shoes!
So, they get hired to pose nude, and they are told to bring sexy shoes. So what do they bring? Their stripper shoes.
A lot of my girlfriends are stripper, so I know from a good source
