Steel stockings are the kind of socks that are very durable and will not be scratched by steel wires. These socks often appear in marketing videos. In general, people in the video will take something similar to a steel ball and scrape it back and forth on the stockings to prove that the socks are wear-resistant and do not rotate.
The earliest clients of stockings were men. In the16th century, European courts and upper classes began to be obsessed with colored pantyhose. According to the fashion at that time, men used to wear pantyhose generously to show their thighs, which was considered as a symbol of beauty. From David's The Coronation of Napoleon I and the Queen, we can see that even on solemn occasions, princes and nobles will show their legs and unanimously choose tight stockings.
