I was a bit befuddled by several reviews stating the shoe is "long in the heel." I couldn't get an image of what this might mean... until my pair arrived. On the plus side, these have excellent support for a ballet flat, very stiff-soled. Unfortunately, they are, in fact, long in the heel. The overall length of the shoe seems about right, possibly a tad small, but when the arch support is correctly positioned, there is a large gap behind the heel. I'm so saddened by this as the shoe appears to be otherwise quite well-made and would be perfect for what I wanted.
