My daughter has skinny feet, so really these aren't the best.  She uses them in her preschool where she has to have clean soles in the classroom.  So they stay at school and I rarely see her in them.  Except when I do I notice her foot at the top has lots of room to move around.  The problem is that the top part is not adjustable.  But the ankle strap is, and she very easily is able to get her shoes on and off.  So no real complaints.  Though of course I wish there were more adjustment options.  Very cute, and sturdy.
