A blucher (pronunciation: /ˈbluːtʃər/ or /ˈbluːkər/, German pronunciation: [ˈblʏçɐ], Blücher) is a style of shoe similar to a derby. Its vamp is made of a single piece of leather ("one cut").
It is named after the 18th century Prussian general Gebhard Leberecht von Blücher. General von Blücher commissioned a boot with side pieces lapped over the front in an effort to provide his troops with improved footwear. This design was adopted by armies across Europe.
