I am becoming a huge fan of ballet flats. I need to give my poor feet a rest from constant 4 plus inch heels! Plus I'll be traveling soon and I'll need comfortable shoes. I also love that these fold up. I am going to start toting them around in my bag. That way I can wear flats when I'm walking to/from my car and slip my heels on when I get to wherever it is I'm going. I really want to order a pair of Sue London flats but I want to make sure I order the correct size. Please help me figure out what size to order. My US size- 8.5 or 8 wide My European size- 38.5 or 39 Here are some examples of my shoe size in some of the shoes I own: Lanvin shiny calf leather ballet flats 39 (I tried on a satin pair in 38.5 that fit too) Chanel elastic ballerinas 39 Misc. Prada shoes 38.5 Misc. Miu Miu shoes 38.5 Jimmy Choo Heidi and Eleven 39 TIA for your help. I am itching to order these so I anxiously await feedback. I love this forum!
