We gave these "slippies" to my 4 year old daughter for Christmas. Of all the other presents that she got that morning, this was the her favorite. In fact, she insisted on wearing them to our Christmas lunch family gathering that day as well. They are very well made and have a rubber sole on them for indoor or outdoor wear. I also like that they have a heel on them, as it prevents her foot from slipping out if she is running in them. Worth every penny!
