What is a "jackboot"?

A jackboot is a type of military boot that is typically made of leather and features a tall, stiff shaft that extends up to the knee or higher. The boot is designed to provide support and protection to the foot and lower leg during combat or other military operations. Jackboots may feature additional elements such as steel toes, reinforced heels, and sturdy soles with deep treads for traction. They are often associated with authoritarian regimes and have a reputation for being heavy and uncomfortable to wear for extended periods of time. Despite this, jackboots continue to be used in military and law enforcement contexts in some parts of the world.
