Blucher shoe

A blucher ( /ˈbluːtʃər/ or /ˈbluːkər/, [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.
