Halle has to have a wicked bunion on her right little toe, I think that's what that is. The toe is more separated than usual from its neighbor, which would create a lot of pressure, discomfort, and callusing if she wore closed-toe footwear all the time, unless it were extra-wide (in which case it might be too loose for her heels and instep).
I count five piggies for knockout looker Halle Berry.
