Sheila's Heels convertible stiletto
Sheila's Wheels, a spinoff division of UK insurance company eSure, has created a pair of convertible stilettos. The company markets insurance to women and found that British women regularly wear inappropriate footwear when driving, so they developed Sheila's Heels, which is a regular stiletto that folds down flat for driving. It even has a grip pattern on the sole for better pedal control. Although I can't imagine a single woman actually buying these. You might as well turn in your vagina and call it quits as a female.
