Toronto's bus stops are popular locations for all sorts of advertising and none are more favoured than the Yonge and Dundas Street glass shelter. Filming was underway in front of the Eaton Centre as they carefully filled the poster box with high heels. There was no title or indication of what they were filming, so I am not really sure what the point of the shoes are yet.
If shoe shopping were this easy, everyone would be taking the bus around town. The shoes looked normal until she put them on - then you won't believe what happened next. Sorry, I got nothing. But sometimes it's fun to write clickbait style. See more unusual bus stop advertising here (giant headphones), here (jungle fun), here (dinosaurs) and here (booze).
