These custom made heel springs, like the ones worn by the protagonist Chell in the Portal video game franchise, don't seem like a very useful creation in real life, but who needs function when the form is so cool, and they're an integral part of a wicked Chell costume? Scifi femme fatale prisoner cosplay FTW!

If only they actually allowed you to survive a long fall, like they do in the game, the creator Harrison Krix would become a very rich man indeed!
