What would you rather: Stiletto or wedge? Gucci or Pucci? Barneys or Bergdorf's? Tough call, right? Now, try answering those Qs on the spot in under five seconds. We put ShoeMint designers Rachel Bilson and Nicole Chavez in the hot seat and fired some tough questions at them in our lightening round. Like we said, they pretty much share a one-track mind, but they definitely have their differences (particularly when it comes to Barneys/Bergdorf's debate). Whose side are you on?
