These are super cute! And because of the adjustable strap, they fit my daughter who started wearing at 4 months old, and still wearing, she's 6 months old now, and plenty of room to grow. I found it difficult to find shoes for a 4 month old, that would actually stay on her feet, and these are perfect. They have never fallen off. I love the whole See Kai Run line, their socks are great too!
