I don't know how I got this idea, but I just did. I was thinking, if you can short sell stocks, can you short sell shoes? So for example, say that red louis Vuitton heels are selling for $1,000 and you think that in a year they'd sell for $5,00. And you find a person that has completely new unworn shoes. You borrow them from her and sell them online for $1,000 and then when they fall to $5,00 you buy them back and return them to the woman + $1,00 in interest. Now she has her shoes and $1,00 in interest. Is this even possible?
