For those times when the world needs to know that you'll exchange sex for money, you can't go wrong with a pair of shockingly-tall, black leather stilettos. But what most hookers don't realize is that you don't have to forgo fitness while you're pacing poorly-lit street corners and schlepping up stair cases to the untidy apartments of lonely pervs.

In fact, you don't even need a separate stair-counter for your working-girl workouts -- all thanks to these new heels from Costume National.

The company was on a mission to combine fashion, technology, and functionality to make an item that felt both classic and contemporary. And while, technically, they've succeeded by cramming a gadget into iconic footwear, we're not sure this was a worthwhile project in the first place -- mostly because the shoes are really ugly.

Would you wear them?
