Crew-length socks cover up a little bit of the ankle while still allowing kids to show their personality with different colours and patterns. These kids novelty socks come in handy when playing sports or any activity involving mobility. Most times, kids will wear these socks when they don't want their feet to feel cold because the fabric is a higher gauge than most children’s socks. Some kids need to wear crew-length socks for medical reasons, like neuropathy or circulation problems, but whatever the reason crew length socks are a good idea if you have small feet or if you need your child's socks to stay put.
