These are simply adorable and I was so excited when I took them out of the box.  The problem is there isn't enough height in the toe area.  My daughter's feet started swelling after just a few minutes.  She is not overweight and the length fit fine (sz 3.5M)but they just ran small, in my opinion.  Maybe a W would be better, but she has narrow feet so I didn't go that route.  Sadly, I have to return them.
