ShoeFitr: The company Amazon must buy immediately
I was initially confused by the demo.<p>Potential use cases<p>1. I have a perfect fitting shoe, I'd like to buy another perfect fitting shoe of a different brand.<p>2. I haven't found the perfect fitting shoe.  I'd like to find one.<p>I assumed this would be solving problem #2, but it solves problem #1.<p>I thought I would tell it "I'm currently in shoe X, and it's the right length but chafes on the right side" or something of that nature, and it would tell me a better shoe.
