custom printed socks

A sock is a piece of clothing worn on the feet and often covering the ankle or some part of the calf. Some types of shoes or boots are typically worn over socks. In ancient times, socks were made from leather or matted animal hair. In the late 16th century, machine-knit socks were first produced. Until the 1800s, both hand-made and machine-knit socks were manufactured, with the latter technique becoming more common in the 19th century, and continuing until the modern day.

One of the roles of socks is absorbing perspiration. The foot is among the heaviest producers of sweat in the body, it can produce over 0.25 US pints (0.12 L) of perspiration per day;^[1] socks help to absorb this sweat and draw it to areas where air can evaporate the perspiration. They also protect shoes, a more expensive, durable, and frequently reworn foot covering, from perspiration, extending their life.

In cold environments, socks made from cotton or wool help warm up cold feet which in turn helps decrease the risk of getting frostbite. Thin socks are most commonly worn in the summer months to keep feet cool.

In men's fashion, light-colored socks are typically worn with sports shoes and dark colored socks with dress shoes (often black or navy blue dress socks). Fanciful sock designs are becoming more common.^[2]

The modern English word sock is derived from the Old English word socc, meaning "light slipper". This comes from the Latin soccus, a term to describe a "light, low-heeled shoe" worn by Roman comic actors,^[3] and deriving from the Ancient Greek word sykchos.^[4]

Socks have evolved over the centuries from the earliest models, which were made from animal skins gathered up and tied around the ankles in the manner of the later Greek and Roman carbatinae shoes. Because the manufacture of socks was relatively time-consuming in preindustrial times, they were long used only by the rich. The poor wore footwraps, simple cloths wrapped around the feet. These remained in use in Eastern European armies until the end of the 20th century.

According to the Greek poet Hesiod, in the 8th century BC, the Ancient Greeks wore socks called "piloi", which were made from matted animal hair.^[5][6] The Romans also wrapped their feet with leather or woven fabrics. Around the 2nd century AD, the Romans started sewing the fabrics together making fitted socks called "udones". By the 5th century AD, socks called "puttees" were worn by holy people in Europe to symbolize purity.

During the Middle Ages, the length of trousers was extended and the sock became a tight, brightly colored cloth covering the lower part of the leg. Since socks did not have an elastic band, garters were placed over the top of the stockings to prevent them from falling down. When breeches became shorter, socks began to get longer (and more expensive). By 1000 AD, socks became a symbol of wealth among the nobility. From the 16th century onwards, an ornamental design on the ankle or side of a sock has been called a "clock".^[7][8][9]

The invention of a knitting machine in 1589 meant that socks could be knitted six times faster than by hand. Nonetheless, knitting machines and hand knitters worked side by side until 1800.

The next revolution in sock production was the introduction of nylon in 1938. Until then socks were commonly made from silk, cotton and wool. Nylon was the start of blending two or more yarns in the production of socks, a process that still continues today.

In recent history, scientific evidence has suggested that wearing socks to sleep can be beneficial in that it helps the individual to fall asleep faster and stay asleep longer. ^[10]

Socks can be created from a wide variety of materials, such as cotton, wool, nylon, acrylic, polyester, olefins (such as polypropylene).^[11] To get an increased level of softness other materials that might be used during the process can be silk, bamboo, linen, cashmere, or mohair.^[11] Merino wool is a popular fabric choice that offers warmth and comfort to socks, and retains its shape better when blended with other materials.^{[12]: 242 } The color variety of socks can be any color that the designers intend to make the sock upon its creation. Sometimes art is also put onto socks to improve their appearance. Colored socks may be a key part of the uniforms for sports, allowing players teams to be distinguished when only their legs are clearly visible.

Fort Payne, Alabama, is regarded as the "sock capital of the world" due to nearly half of socks manufactured in the early 21st century were made here. The Fort Payne sock industry employed about 7000 workers at its peak around the year 2000.^[13] Fort Payne, while still one of the largest producers of socks, only produces only a quarter of all socks, and has lost that title to Datang, China.

The township-level district of Datang in the city of Zhuji in Zhejiang Province, People's Republic of China, has become known as Sock City. The town currently produces 8 billion pairs of socks each year,^[14] a third of the world's sock production, effectively creating two pairs of socks for every person on the planet in 2011.^[15]

Socks are manufactured in a variety of lengths. No show, low cut, and ankle socks extend to the ankle or lower and are often worn casually or for athletic use. No show and low-cut socks are designed to create the look of bare feet when worn with shoes (sock not visible). Knee-high socks are sometimes associated with formal dress or as being part of a uniform, such as in sports (like football and baseball) or as part of a school's dress code or youth group's uniform. Over-the-knee socks or socks that extend higher (thigh-high socks) are sometimes referred to as female garments in the common era. They were widely worn by children, both boys and girls, during the late 19th and early 20th centuries; although, the popularity varied widely from country to country.^[16] Knee-high or thigh-high socks are sometimes the object of sexual attraction and underwear fetishism.^[17] Liner socks are socks which are worn underneath another sock with the intention being to prevent blisters.

Toe socks encases each toe individually the same way a finger is encased in a glove, while other socks have one compartment for the big toe and one for the rest, like a mitten; most notably what Japanese call tabi while other parts of the world simply call it split toe socks. Both of these allow one to wear flip-flops with the socks.^[18]

Leg warmers, which are not typically socks, may be replaced with socks in cold climates and are similar to leggings due to the fact that they typically only keep legs warm in cold weather but not the entire foot.

A business sock or dress sock is a term for a dark-colored sock (typically black or navy blue) for formal or casual footwear. It is often loosely referred to as a work sock or a formal sock for formal occasions, for example, weddings, funerals, graduation ceremonies, prom, church, or work.

Crew socks are short and thick or thin everyday socks. Those socks are usually ribbed at the top of the ankles.^[19][20] They can be used in a way to warm legs if pulled all the way up.^{[21][clarification needed]} The first familiar practice of crew socks^{[clarification needed]} was in 1948.^{[citation needed]} Crew socks are usually unisex.^[22]

A low cut sock is a kind of sock that describe in a way to be cut below the ankle. Low cut socks are formed to cover the contours of a person's feet. Although low cut socks are unisex, women and girls commonly use them. Low cut socks are normally worn with shoes such as boat shoes, Oxfords, moccasins and loafers.^{[citation needed]}

The Ancient Egyptian style of sock is a blend between modern Western socks and Japanese tabi, both of which it predates. Like tabi, Egyptian socks have one compartment for the big toe and another for the rest, permitting their use with sandals. Like Western socks, they fit snugly to the foot and do not use fasteners like tabi.
