Socks are a type of footwear. They are worn on people's feet most of the day, and they come in different colors and sizes. Two socks form a pair only if they have corresponding color patterns and the same size. Each sock is a member of a pair, although the other member may sometimes be missing, or may even no longer exist.

Colors
Socks may have any color. A sock may, but does not necessarily, have more than a single color. However, strong colors are less common, especially on larger socks. Larger socks tend to be either white, gray or black, or a color close to one of these, with few other colors on them.

Sizes
The sizes of socks may vary a lot. This is due to the fact that people may have very differently sized feet, depending on age, gender and other factors. For each foot, there should exist a sock whose size is such that:


 * One should be able to take it on or off the foot with little effort
 * There should be very little room to spare while the sock is being worn by the foot

Worn out socks
Socks tend to wear out after a while. This is usually seen as additional holes appearing on the socks. These holes tend to be located at either the toes or the heel. More than three such holes is uncommon.

Holes at the toes
Such holes are usually made by the big toe, although such a hole may be located near the little toe as well. That is because the same sock can we worn on either foot, so a hole near the little toe may previously have been near the big toe of the opposite foot. A sock may therefore have two such holes: One on each side − each of which has been made by a different big toe. Socks wear out more quickly if the big toes have long nails.

Hole at the heel
A hole may appear at the heel after a lot of walking, due to the pressure from the heel.
