I am on the hunt to find these Jimmy Choos in my size I am a 39-39.5 in Jimmy Choo & I would loveee to take these to Greece with me this summer, but cant find my size! They are on sale at Saks even Net-a-Porter but no size 39-39.5. Im not sure if a 40 will be ok. He does seem to run a bit small/narrow. I found a 40 on eBay but scared that they might not fit. Please help me find them!!! Thank you!!!!!!
