These shoes are STUNNING! I ordered size 38 and it fit perfect. They are extremely comfortable and worth every penny! I did end up returning mine only because I think I want to get the ones with the bigger heel.
I personally hate kitten heels. I ordered these for my Paris trip knowing I'll be doing a lot of walking. I was pleasantly surprised how beautiful these pumps are. The heels are super low so this makes a perfect pair of pumps to walk around in while still looking polished. The 3 ankle straps are to die for. Absolutely gorgeous and very comfy. Unfortunately I had to return because it was a tad too small. Order a half size up. I'm usually a size 36 and I have the Valentino rockstud pumps with the higher heels in a size 36, which fit perfectly. I don't know if it's the lower heel, maybe because your feet are sitting more horizontal, but I needed a 36.5 for these pumps.
LOVE, LOVE, LOVE and own them in red, tan and black. I have worn these shoes for parties and for work events. I always get compliments on them like crazy from the ladies and men check them out constantly. The heel height makes them perfect for walking for long periods. I find them very comfortable. It took me just a couple of hours to break them in on my first night out with them and I can wear them now anytime without any discomfort, they have totally molded to my feet. I have business events and meetings in London often and I find it hard to get a great pair of shoes that look amazing and still let me walk all over the place. These are now my first choice when I fly to that city and have events to attend. The price point is of course high and it really depends on your budget but the quality is great and I wear mine all the time. I am usually a 10.5 I ordered the 41 and it was a great fit.
