Socks
Nearly everyone in the world uses socks and that is because they are extremely practical and useful. Protecting the feet from the cold is extremely important in places where the weather is cold for longer than it is warm. They also help keep the feet dry by absorbing sweat that the feet produce, which in turn helps to keep bacteria and fungus from growing. These wonderful articles of clothing also help reduce the friction between the feet and shoes when walking or running.
Socks can come in a wide variety of choices and options for any occasion and are generally accepted everywhere. Some people may have issues with using them with sandals, however, but then again some people find them comfortable even then. From knee high to crew cut, they come in all sizes. There are even therapeutic socks available for people with diabetes or other issues with the legs including circulation.
