"I own many pairs of Anne Klein pumps and this is the first pair of shoes I've ever had to put all kinds of cushioning and heel grabbers in to keep them on. I would absolutely say the 6.5 is more like a 7. I can stuff enough things in there to keep it on, but it's still loose. Definitely size it down a half size.
Otherwise - it's an amazing design that I get complimented on every time I wear them. Which would be more often if the fit was right!!"
