While traveling on the bus, I saw a beautiful girl with silky legs and huge feet in ballet flats. Although I didn't have the opportunity to see her bare feet, it was obvious at first glance that they must be huge. Still, I kept wondering what her specific foot size was and I think I've come up with an almost perfect way to find out. I measured the holes in the rubber mat she was standing on and concluded that her foot size was between a 12 and 12.5 US! This is a dream. As well as being able to sniff her bare soles after wearing those shoes all day.
