The shoe is beautiful looking, I actually did not have the size problem I saw with other reviwers. I am a size 12 and bought just that and it works well, it may of course well be because of the bit of fabric which gives you room.  I am going to agree that the thin soles is a bit of a worry, the front tip is wearing down already and so I anticipate taht there will be problem with this.  This is the reason why I would not go beyond a 3, shoes after all are made for walking in.
