I bought these for my 7 year old daughter. She wears a size 2-3. I bought a 3 so she could wear these for awhile. She had a little room for growth but they don’t slip at all.These are easy slip ons for school. They have good traction that help avoid slipping on the muddy fields at recess. They don’t slip off her heel and she says they are very comfy. These are the shoes she reaches for most often.These ran small and the back of the shoe cuts in to the child's ankle.I give it 2 Stars cuz it's still a coolish shoe but the shoe shipped and thare we're good un tell the shoe was too small like bad the shoe is the same size as a 3 youth maybe a little smaller
