Socks became a common everyday garment for most people during the Industrial Revolution in the late 1700s and early 1800s, when knitting machines made mass production possible for the first time. Before that, socks existed for thousands of years but were either handmade at home or expensive enough to mark social class. The full story stretches from ancient Egypt to the invention of nylon, with each leap in technology pushing socks closer to the universal wardrobe staple they are today.
Ancient Foot Coverings: 2,000+ Years of Socks
The oldest surviving socks date to roughly the 3rd or 4th century and were found in Egypt. These weren’t knitted in the way we’d recognize. Ancient Egyptians used a single-needle looping technique called nålbindning, threading yarn through loops one stitch at a time by hand. The result was a thick, durable fabric. Many of these early socks had a split between the big toe and the other four toes, designed specifically to be worn with sandals.
Romans wore socks too, calling them “udones.” These were made from pieced-together cloth or woollen yarn, sometimes with open toes and heels. Archaeological finds across the Roman Empire confirm how widespread the practice was. At Vindolanda, a military outpost just south of Hadrian’s Wall in northern England, a preserved letter from around 1,800 years ago includes a care package list: pairs of socks, sandals, and underpants. In Southwark, on the south bank of the Thames, archaeologists found the sole of a Roman sandal with the impression of woollen cloth still preserved in the rust of its hobnails. A bronze statue foot uncovered nearby clearly shows a sock worn underneath a sandal. Romans, it turns out, were fully committed to the socks-and-sandals look.
Medieval Socks: A Luxury for the Wealthy
Through the Middle Ages, socks took on a new role as a status symbol. Nobles wore stockings made from fine fabrics like silk, often decorated with elaborate embroidery. For everyone else, socks were simpler, made from coarse wool or flax and typically produced at home. The craft was entirely manual, which meant production was slow and fine materials were expensive. A well-made pair of silk stockings could represent real wealth.
This split between luxury hosiery for the upper classes and rough homemade socks for ordinary people persisted for centuries. Socks were common in the sense that most people wore some form of foot covering, but anything resembling a comfortable, well-fitted sock remained out of reach for the average person.
The Knitting Frame Changes Everything
The first major technological shift came in 1589, when an English clergyman named William Lee invented the stocking frame, a mechanical knitting device that could produce hosiery far faster than hand knitting. This machine didn’t immediately make socks cheap or universal, but it laid the groundwork. For the next two centuries, stocking frames were refined and spread across England and continental Europe, gradually increasing output and lowering costs.
In 1816, a circular knitting machine called the tricoteur was invented, allowing tube-shaped fabric to be produced continuously. This was a critical step toward modern sock manufacturing. By the time the Industrial Revolution was in full swing during the late 18th and early 19th centuries, knitting machines enabled true mass production. Socks became accessible to people across all social classes for the first time. Factory-made hosiery was cheaper, more uniform, and available in quantities that hand knitting could never match. Knitting machines were considered so valuable that early American manufacturers had to smuggle them out of England, where export restrictions tried to protect the British textile industry’s advantage.
By the 1840s, another small but meaningful innovation arrived: elastic cords that held stockings up above the knee, replacing ties and garters that had been used for centuries. Socks were becoming not just affordable but genuinely practical.
Nylon and the 20th-Century Boom
The next revolution came with synthetic fibers. When DuPont announced nylon in 1938, the textile world shifted permanently. Nylon was stronger, more elastic, and more resistant to mildew than natural fibers. The first nylon stockings went on limited sale in Wilmington, Delaware, in October 1939 and hit the national market on May 15, 1940. Within two years, DuPont had captured 30% of the full-fashioned hosiery market.
World War II briefly redirected nylon production toward military uses, where its strength and light weight proved valuable. But by the 1950s, nylon and other synthetics flooded the consumer market. Socks, underwear, sweaters, and countless other garments could now be produced cheaply using blends of natural and synthetic fibers. The promise was simple: easy-care, wash-and-wear clothing at prices nearly anyone could afford. This era cemented socks as a disposable, everyday commodity rather than something worth mending or carefully maintaining.
Regional Variations Took Their Own Path
Not every culture followed the same timeline. In Japan, tabi socks date back to the 15th century and evolved from leather shoes. The split-toe design emerged during the late Heian period (794 to 1185) to accommodate the thong of traditional sandals, much like those ancient Egyptian socks from over a thousand years earlier. Because most Japanese footwear was thonged, tabi were worn widely across Japanese society, making them one of the more universally adopted sock forms in any single culture.
Across most of the world, though, the pattern was consistent: socks existed in some form for millennia, remained a luxury or homemade necessity until mechanized knitting arrived in the 1600s through 1800s, and only became truly universal with industrial mass production and synthetic fibers in the 20th century. The sock you pull on without thinking each morning is the product of roughly 1,700 years of gradual refinement, from a hand-looped Egyptian toe sock to a factory-made cotton-nylon blend produced by the millions.
