Blucher shoe
A blucher ( or , German pronunciation: [ˈblʏçɐ], Blücher) is a style of lace-up shoe with its vamp made of a single piece of leather ("one cut"), atop which are sewn its eyestays, which contain the shoelace eyelets, an attribute called "open lacing." The blucher is similar to a derby since both feature open lacing, in contrast to the Oxford shoe, which fastens the vamp on over the eyestays ("closed lacing"). However, in the derby, the upper's vamp is separate from its large quarters, while in the blucher, the upper is made of one cut.
