Also known as: 短袜
Socks that are at "ankle length".
Despite the name, the tag refers to socks that are slightly above the ankles, not low-cut or No-Show Socks that stop below the ankles. They end before the shins; if they go over the shins, they become Kneehighs.
Not to be confused with Booties, a sock-like garment that is also ankle length.
