During the Song Dynasty, socks became more diverse, including long socks, short socks, and layered socks, catering to different occasions and clothing combinations. Song Dynasty socks were known for their intricate craftsmanship, often featuring embroidery and woven patterns.
In the Ming (1368–1644 CE) and Qing Dynasties (1644–1912 CE), as the textile industry further developed, cotton socks became common among the general population. Particularly in southern China, where cotton was widely grown, these socks became a staple for warmth and comfort.
Additionally, during the Ming and Qing Dynasties, officials and scholars wore silk socks, symbolizing status and wealth. These socks were often elaborately designed and exclusive to certain social classes.

The Social Symbolism of Socks in Europe:

By the 14th century, socks had become a key status symbol among the European aristocracy. King Charles V of France famously wore luxurious silk stockings and popularized them in his court, a trend that quickly spread across European royalty.
Socks of this era were crafted from fine materials and adorned with intricate patterns and colors, often symbolizing different noble houses or ranks.

3. Technological Innovations and the Industrial Revolution in the Early Modern Period

William Lee’s Invention of the Knitting Machine (1569):

In 1569, English clergyman William Lee invented the first knitting machine, marking the beginning of mechanized sock production. This machine could knit thousands of stitches per minute, significantly increasing production speed and quality.
Despite initial resistance from workers and investors, Lee’s invention laid the foundation for the modern sock industry as the machine was gradually improved and widely adopted.
