Invisible boat socks, also known as "invisible socks" or "boat socks". Originally originated in Japan, socks with open instep are used for indoor barefoot wear. Because they look like boats when put on, they are named "boat socks". Different from ordinary socks, boat socks are usually short in length, and the sock mouth is often below the ankle. The name "boat socks" is because socks are shaped like a boat. In Hong Kong, Macao and Taiwan, it is often called "invisible socks", because after wearing shoes, it usually covers only the first half of the foot, and socks are often invisible.
Boat socks, popular in Europe and North America, are ankle-exposed socks, which visually make people feel that they have no socks and are suitable for most casual shoes. This kind of boat socks can save men from the embarrassment of heavy activity, sweaty feet and bad smell in summer.
Boat socks appeared in the early1980s, when tennis clothes began to rise. The classic style has two fur balls at the ankle, which was popular again in the mid-2000 s, but many styles have been changed, mainly used to match skateboarding clothes, followed by shorts or short skirts. Some girls wear contact socks because they want to fully show the curve of their legs. Socks are not good-looking, so they are usually worn when they are exercising or walking in the leisure style, usually with shorts or hot pants.
