"A derby (UK: /ˈdɑːrbi/ (listen) DAR-bee, US: /ˈdɜːrbi/ DUR-bee; also called gibson[citation needed]) is a style of boot or shoe characterized by quarters, with shoelace eyelets that are sewn on top of the vamp. This construction method, also known as "open lacing", contrasts with that of the Oxford shoe.[citation needed]
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.[citation needed]" - (en.wikipedia.org 24.09.2021)
