This is the second pair of Kina's I purchased for my son. The first pair I bought at a small boutique in my area. These booties truly stay on his feet and keep him warm too. His first pair I bought was when he was about 5 months and this pair is still going strong at 17 months old. I highly recommend them to all my friends. The story behind the Kina Collection is very touching! I would not recommed them as an outside shoe. We primarily use them as slippers inside the house or in his stroller when we are out for a walk.
