I think they run true to half sizes.

My foot is a size 5 1/2 so I typically buy shoes in size 6 to give my toes and bunions room. Their sizes indicated that a Euro 36 was a US size 5 - 5 1/2, and a Euro 37 was a US 6 - 6 1/2. I bought the Euro 37 and it was way big for me (about an inch). To me they seem to run truer to the half size. I was afraid the size down (Euro 36) would be a true size 5 1/2 and not give my toes and bunions any room to spare. I decided to return them and not go through the hassle and cost of exchanging them just to have to return them again. Plus they didn't really fit the purpose I bought them for.

I gave them a 4 star because they are a super cute and comfy bootie.
