Depends on the shoe. Heels are all about shaping the leg, but if they themselves are poorly shaped, then the whole effect is ruined.
Also, different types of people can pull off different types of heels. Someone with a more squat frame might WANT to be taller, but would be better served by smaller heels.

In any case, there is no way in HELL these cursed things would look good on ANYONE. I can't look at that and not feel sympathetic pain!
