the great heel debate - what can you handle?

We've all been there: buying a killer pair of heels because they look so amazing in the store, only to realize they're painfully unwearable the first time we actually step onto the sidewalk.

Whether it's in the mall or on the runways, heel heights slowly have been creeping up to Mount Everest proportions. But wearing these gorgeous shoes can cause some not-so-pretty consequences.

Want proof? This season at the Burberry show, their monstrous stilettos caused one model to topple right over! And she's not the only one- everyone from Naomi Campbell to Agyness Deyn have fallen on the catwalk, thanks to impossible footwear.

Maybe it's no coincidence then, that while designers like Christian Louboutin are sticking with sky-high pumps, others, like Nicholas Kirkwood, are instead opting more practical designs, like the kitten heel.

We've rounded up some of our favorite options, from the extravagantly high-fashion to the down-to-earth (pun intended), and want to know: what's your maximum heel height?
