I purchased these for my daughter. Her feet are about a 5.5 in women's. I was pleased when they arrived so soon. They were really cute and looked very comfortable. The problem? My daughter could not even begin to put her foot in the slipper because it was so small. NOW, it is possible that her feet are growing more rapidly than we know so, I hesitate to write the review. All the same, she literally could not put her foot in the slipper. That seems odd to me. Even I can put my foot in a shoe that is 1 size too small. This leads me to believe the size is off a bit.
