These are the perfect little slippers for toddlers to slip on when they just want to run around without the putting on shoes. We use them inside and outside of the house, when my g-daughter wants to go out on the deck and play or just running around the house on the hard wood floors. They are warm and have a hard sole so they are perfect for hard floors inside and outdoors on the deck. Easy for her to put on and take off. They were thicker and heavier than I thought based on the description and the image. She will outgrow them before they wear out.
