It's actually sorta fun. Here's a pair of "Lezlie" heels before:
... And after I got done customizing my very own:
They'd be $129, which is a not unreasonable price to pay for shoes (in this case at least) so ridiculously tacky that they're almost awesome. You pick the upper, buckle, trim and heel color, and you pick the size, of course. I was pretty surprised to find that Steve Maddens, at least these and I'm sure most other styles, are available in as small as size 4 (which I haven't been since I was in about third grade) and they go up to size 12. Fun!

The Nlight comes in 15 different color combos to begin with, but you can also trick it out accordingly.
