These are first shoes luxuriously sewn from sheepskin. They will warmly wrap your child's feet, such as when being held or going out in a stroller. They can be used not only as first shoes, but also as indoor shoes or in place of socks. The size is not indicated, but it seems to be for babies around 1 to 1.5 years old. I apologize that I don't know because they were a gift, although it may be written somewhere. They are unused, but please refrain from purchasing if you are concerned about minor details due to home storage. I will ship them in the outer box shown in the photo.
