Children’s sock sizes by age – The Ultimate Free Size Chart Builder for Woocommerce

To help you pick the right sock size, a Kids Socks Size Chart is necessary as socks come in many sizes. A newborn will need a baby sock, a few sizes larger. A toddler or youth sock is designed to fit a child with a shoe size of two to six. A child of eight years and up should wear a youth or medium sock.
