I've been wondering the same thing. These Dolce Vita patent flats also look exactly the same as the Nine West ones I was considering earlier. I never tried the NW ones on because I couldn't find them in the color I wanted. But they did look exactly like this and the sole was just as thin.
I am curious. I really liked the nine west ones but i was going to have to spend atleast $25 to reinforce the sole w/rubber and they just were not worth it.
