Hello all! So I have the simple pump in black. I'm debating between the nude simple in the 85mm heel or the Sophia Regina. Here is the link for it: http://eu.christianlouboutin.com/uk_en/shop/women/sophiaregina-patent.html Would the size for those be the same as the simple pump? Would you recommend the new simple nude with the platform? What about the Fifi? What do you all think? What's the most comfortable?
