Derby Shoes

In American English the derby shoe may be referred to as a blucher, although technically the blucher is a different design of shoe where only eyelet tabs (not larger quarters) are sewn onto a single piece vamp.
In modern colloquial English, the derby shoe may be referred to as “bucks,” when the upper is made of buckskin.
The derby became a popular sporting and hunting boot in the 1850s. By the turn of the 20th century, the derby had become appropriate for wear in town.
