If we're specifying that they must be worn in public, it'd be either these or the same boot with the flames in deep purple.

I've got the knee length version with red flames and have been out in those a couple of times.
Without that restriction it'd be a black suede fitted knee boot, made to measure, with a full-length back zip, pointed toe and solid steel five inch stiletto heel. I doubt I'd ever find those though, and I couldn't afford to have a pair custom made!
