The term 'bootstraps' appears to have originated in the early 19th-century United States (particularly in the phrase "pull oneself over a fence by one's bootstraps").

Tall boots may have a tab, loop or handle at the top known as a bootstrap, allowing one to use fingers or a boot hook tool to help pulling the boots on. The saying "to pull oneself up by one's bootstraps" was already in use during the 19th century as an example of an impossible task.

Today it is also used as a design element and to hang shoes out to dry.
