Children's socks are generally sized according to their age and shoe size. Socks come in a variety of colors, patterns and styles for both boys and girls. Sock sizing can be somewhat difficult due to the fact that sock sizes are different from shoe sizes. Sock sizes are based upon the length of the foot while shoe sizes are based upon the length of the shoe. This can create problems when shopping, so it is important to be aware of this fact before making your children's sock purchases.
