I have a pair of Puma Wedge Booties in an 8.5. so I ordered these in an 8.5 but they were entirely too small. I am typically a 9.5 but since I have another pair of Puma's I assumed the brand ran the same sizes. I was wrong. The shoes are lovely, but I suspect this particular style runs true to size. I just hate that they do not carry any Fluorescent Pink (which is what I purchased) or Fluorescent Yellow or Orange Popsicle in any sizes other than 8.5
