My son is 11 months old and I have tried so many different booties, shoes and socks and nothing would stay on his feet. He would just pull them right off. These stay on all day!! He cant get them off! They are super cute and soft. They are a little hard to get on, but after messing with them a few times I got the hang of getting them on his feet. I will definitely be buying the next size up when he grows out of these.
