We have used these socks exclusively for our son since he was about 9 months old because they're the only ones that don't fall down and bunch up on the bottom. They are warm and he seems to think they're comfortable. The little red Hanes and sock size help provide a little non-slip grip. I only wish they came in different colors aside from white with gray/blue. But we love them and will use them for years to come! I'm reading a lot of parents think the socks are too tight. These ankle socks are shorter than the regular and they don't pinch my sons legs too much at all. He's smaller than average though so maybe his legs aren't as chunky.
