Question: what are men's derby shoes?
Answer: A derby (UK: /ˈdɑːrbi/ ( listen) DAR-bee, US: /ˈdɜːrbi/ DUR-bee; also called gibson) 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.
