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. Machine-knit socks were first produced in the late 16th century. 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 {{convert|0.25|USpt|L}} of perspiration per day.<ref>{{cite news |url=http://health.howstuffworks.com/question514.htm |title=Howstuffworks "Why do feet stink?" |newspaper=Howstuffworks |date=16 November 2000 |publisher=Health.howstuffworks.com |access-date=2010-03-05 |archive-date=2009-08-30 |archive-url=https://web.archive.org/web/20090830122329/http://health.howstuffworks.com/question514.htm |url-status=live }}</ref> 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, warm socks help people avoid getting cold feet, which in turn helps decrease the risk of getting frostbite.<ref>{{Cite web |title=Frostbite: Signs & Symptoms, Stages, Treatment & Prevention |url=https://my.clevelandclinic.org/health/diseases/15439-frostbite |access-date=2025-08-24 |website=Cleveland Clinic |language=en}}</ref> 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.<ref>{{cite news|url=https://nationalpost.com/news/trudeau-socks-holland-shoes-canadian-leaders-quirky-styles|title=Trudeau's socks, Holland's shoes: A look at Canadian leaders and their quirky styles|work=National Post|date=2 February 2024}}</ref>

== Etymology == 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,<ref>{{cite web |url=https://penelope.uchicago.edu/Thayer/E/Roman/Texts/secondary/SMIGRA*/Soccus.html |title=LacusCurtius – Roman Shoes – Soccus |publisher=Penelope.uchicago.edu |access-date=2010-03-19 |archive-date=2022-09-30 |archive-url=https://web.archive.org/web/20220930004936/https://penelope.uchicago.edu/Thayer/E/Roman/Texts/secondary/SMIGRA%2A/Soccus.html |url-status=live }}</ref> and deriving from the Ancient Greek word ''sykchos''.<ref name="online_etymology_dictionary">{{cite web|title=Sock.|url=http://www.etymonline.com/index.php?allowed_in_frame=0&search=sock&searchmode=none|publisher=Online Etymology Dictionary]|access-date=August 28, 2012|archive-date=November 5, 2013|archive-url=https://web.archive.org/web/20131105223013/http://www.etymonline.com/index.php?allowed_in_frame=0&search=sock&searchmode=none|url-status=live}}</ref>

The knitter of this sock started work at the toe and then worked up towards the leg. The heel was made last and then attached to loops formed while knitting the leg. This practice allowed the heel to be easily replaced when it wore out.

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.<ref>{{cite book |author=<!--Staff writer(s); no by-line.--> |title=Take Me Back |location=New York, New York |publisher=Dorling Kindersley Limited |page=[https://archive.org/details/isbn_9780756640903/page/292 292] |date=2008 |isbn=978-0-7566-4090-3 |url=https://archive.org/details/isbn_9780756640903/page/292 }}</ref><ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.01.0132%3Acard%3D536 Hesiod, Works and Days, 542]</ref> 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 AD 1000, 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".<ref>{{cite web |url=http://www.merriam-webster.com/dictionary/clock%5B3%5D |title=clock3 |publisher=Merriam-webster.com |date=2007-04-25 |access-date=2010-03-05 |archive-date=2011-11-16 |archive-url=https://web.archive.org/web/20111116014230/http://www.merriam-webster.com/dictionary/clock%5B3%5D |url-status=dead }}</ref><ref>{{cite web|url=http://www.blacksocks.com/historyofsocksus.htm|title=historyofsocksus|publisher=www.blacksocks.com|access-date=2015-01-03|archive-date=2015-04-09|archive-url=https://web.archive.org/web/20150409203445/http://www.blacksocks.com/historyofsocksus.htm|url-status=live}}</ref><ref>{{cite web|url=https://www.lonelysock.com/SockHistory.html|title=Sock History|publisher=archive of www.lonelysock.com|url-status=dead |archive-url=https://web.archive.org/web/20160929210600/https://www.lonelysock.com/SockHistory.html|archive-date=2016-09-29}}</ref> The invention of a knitting machine in 1589 meant that socks could be knitted faster.

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.

===Footwraps=== [[File:FootClothFromFinnishDefenceForces.JPG|thumb|Footwraps used by the Finnish Army until the 1990s]] Footwraps, pieces of cloth that are worn wrapped around the feet, were worn with boots before socks became widely available.

== Types and styles == [[File:Yellow-green toe socks.jpg|thumb|Toe socks]] [[Image:Flip-Flops socks.jpg|thumb|Flip-flops socks]]

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.<ref>{{cite web|title=End of an era: knee high socks face defeat|url=http://www.easier.com/117407-end-of-an-era-knee-high-socks-face-defeat.html|date=August 19, 2013|access-date=January 3, 2015|archive-date=March 2, 2021|archive-url=https://web.archive.org/web/20210302142943/https://www.easier.com/117407-end-of-an-era-knee-high-socks-face-defeat.html|url-status=live}}</ref> Knee-high or thigh-high socks are sometimes the object of sexual attraction and underwear fetishism.<ref>Boothby, Richard.

===Toe socks=== Toe socks encase each toe individually the same way a finger is encased in a glove. Some other socks have one compartment for the big toe and one for the rest, like a mitten, such as Japanese ''tabi'' or, in other parts of the world, split-toe socks. Both of these can be worn with flip-flops with the socks.<ref>{{cite book|last=Marshall|first=John|title=Make Your Own Japanese Clothes: Patterns and Ideas for Modern Wear.|year=1988|publisher=Kodansha International, Ltd.|location=Tokyo|isbn=0-87011-865-X|pages=108–114|url=https://books.google.com/books?id=ljOuuy0OO0UC&q=japanese+tabi&pg=PA108|access-date=2020-10-20|archive-date=2022-01-30|archive-url=https://web.archive.org/web/20220130152259/https://books.google.com/books?id=ljOuuy0OO0UC&q=japanese+tabi&pg=PA108|url-status=live}}</ref>

===Business and dress socks=== 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.<ref>{{Cite web |title=Definition & Meaning of "Dress sock" in English {{!}} Picture Dictionary |url=https://dictionary.langeek.co/en/word/216685?entry=dress%20sock,%20https://dictionary.langeek.co/en/word/216685?entry=dress%20sock |access-date=2026-03-03 |website=dictionary.langeek.co}}</ref>

===Low cut socks=== A low cut sock is a kind of sock that finishes below the ankle. Low cut socks are formed to cover the contours of a person's feet. Low cut socks are discreet and often worn with a variety of shoes, including sneakers, loafers, and even dress shoes.<ref>{{Cite web |title=Definition & Meaning of "Low-cut sock" |url=https://dictionary.langeek.co/en/word/216686?entry=low-cut%20sock,%20https://dictionary.langeek.co/en/word/216686?entry=low-cut%20sock |access-date=2025-08-24 |website=dictionary.langeek.co}}</ref>

===Egyptian socks=== 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''.<ref>{{Cite web |last=Garton |first=Christina |date=22 May 2020 |title=Wearing Socks with Sandals in Ancient Egypt |url=https://pieceworkmagazine.com/wearing-socks-with-sandals-in-ancient-egypt/ |access-date=2025-08-24 |website=PieceWork |language=en}}</ref>

===Thermal socks=== For use in cold environments, thermal socks are thicker. They are commonly worn for skiing, skating, and other winter sports. They provide not only insulation, but also greater padding due to their thickness.<ref>{{Cite web |date=2024-10-29 |title=Exploring the Benefits of Thermal Socks for Outdoor Winter Adventures |url=https://theglossymagazine.com/exploring-the-benefits-of-thermal-socks-for-outdoor-winter-adventures/ |access-date=2025-08-24 |website=Glossy Magazine |language=en-GB}}</ref>

== Religious significance ==

===Christianity=== A sock is also used as a holiday item during Christmas. Children hang a large ceremonial sock called a Christmas stocking by a nail or hook on Christmas Eve, and then their parents fill it with small presents while the recipients are asleep. According to tradition, Santa Claus brings these presents to well-behaved children, while naughty kids instead receive coal.<ref>{{cite book|last=Bowler|first=Gerry|title=The World Encyclopedia of Christmas|year=2000|publisher=McClelland & Stewart|location=Toronto|isbn=0-7710-1531-3|page=[https://archive.org/details/worldencyclopedi00gerr/page/156 156]|url=https://archive.org/details/worldencyclopedi00gerr/page/156}}</ref>

===Islam=== Among Muslims, socks have initiated a discussion about the intricacies of wudhu, the formal washing carried out before prayer. Some Muslim clerics, mindful of possible hardship among Muslims in inhospitable circumstances, have issued Muslim edicts permitting practicing Muslims to wipe water over their sock or sprinkle their sock.<ref>{{cite book|title=Personal Security: A Guide for International Travelers |page=25 |first=Tanya |last=Spencer |year=2013}}</ref> This would allow prayer where there are no seating facilities, or if there is a queue. This is the stated opinion especially of Maliki Sunnis.<ref>Al-Muwatta Of Iman Malik Ibn Ana – Page 14, 2013 Anas</ref>

== Other uses of the word and slang == The layer of leather or other material covering the insole of a shoe is also referred to as a sock. When only part of the insole is covered, leaving the forepart visible, this is known as a half-sock.<ref>{{cite web |url=http://www.freepatentsonline.com/6044497.html |title=Half sock: Patent 6044497 |publisher=Freepatentsonline.com |date=1998-08-17 |access-date=2010-03-05 |archive-date=2011-06-14 |archive-url=https://web.archive.org/web/20110614050947/http://www.freepatentsonline.com/6044497.html |url-status=live }}</ref>

Young people on social media commonly refer to non-slip hospital socks as "grippy socks". Slang terms for in-patient psychiatric hospitalization may include "grippy sock vacation", "grippy sock palace", "grippy sock jail", and "grippy sock hotel". Mental health professionals have expressed concern that such black humor may trivialize or romanticize the experience of psychiatric hospitalization.<ref>{{cite web |last=Gliadkovskaya |first=Anastassia |date=22 April 2022 |title=This online trend seems to glamorize psychiatric hospitalization.
