A jackboot is a soldier’s boot that comes up to the knee. It is heavy, usually leather, the kind of tall military boot you might see in an old army photograph or a museum. In English the word has a strong second life: people say “jackboot tactics” or that a country is “under the jackboot” when they mean rule by soldiers, fear, and force, not just . That stretch became especially sharp in the twentieth century, when the boot stood in for brutal army power. So if you only mean a tall boot in a fashion shop, knee-high boot is the cooler, more neutral phrase; jackboot drags soldiers — and often cruelty — into the room. The jack here is not the man’s name; it goes with an old word for a protective military coat.
長筒軍靴（穿到膝蓋的士兵靴）。英文也常用來比喻暴力、高壓的統治，不只是鞋子。
