I also have the Rascassa and Rose of this brand and although they do run a little small, my feet are very narrow so I went with my true size for all three. The other two fit ok but this runs very very small. My feet are sticking out quite noticably in these but the real issue I have  is that my pinky toe sticks out of the cut out in the front of the shoe and this is very uncomfortable. I'm not sure if anyone else experiences this but my feet is in no way weirdly shaped or anything so I'm not sure why this is happening. I may need to find something to cover the hole to make it wearable. Also, the front of the shoe digs into my feet when I walk; I don't think I'll be walking long distances in this which is quite disappointing because the sole purpose I purchased this was to have a comfortable summer wedge to wear out on days I don't want to wear 4 inch heels. I'm still debating whether to return this
