Heels, flats or wedges?

I think we can all agree that a girl wearing shoes or boots during sex is incredibly sexy, so this poll isn't about whether or not that is the case, but what type of shoe/boot do you find sexier?

I personally love wedge heels and feel that they aren't worn enough by girls. Something about them just gets me going for sure! I also find at times that flats can be really cute on a girl too and don't get in the way as much during sex.
