Those first two are just plain ugly, I don't care who designed them, they look like something the Wicked Witch of the West may wear to a cocktail party, kind of a sl*tty/matronly thing going on...not good.
The next pair, with the extremely high instep (or whatever it's called) aren't really what I'd call tacky, but I can't see those being worn tastefully too easy. Maybe, but highly unlikely.
The Pigalles were actually an exception for me, I never really liked heels higher then the standard 4 inch spike, but something about the architecture of the shoe makes it very appealing and unthreatening. I'd hardly regard it as genius, just very brave on Louboutin's part, to introduce something reserved mainly for strippers, p*rn stars and fetish shops into high fashion with such popular results.
The other Louboutin just has a certain vintage appeal about it, very 40's pin-up, which is just enough sex with a touch of class....but I think less approachable then the Pigalle because of the shape, it may be too "costumey" or something like that.
And the last pair just seem like a knockoff of the Pigalle, so I can't say I have a problem with them at all.
