Derbies are a type of formal shoe that are typically made of leather and have a closed lacing system. Synonyms for derbies include oxfords, brogues, wingtips, and bluchers. Oxfords are similar to derbies in their overall design but typically have a tighter, more contoured lacing system. Brogues are a type of derby that features noticeable perforations or patterns in the leather along the edges of the shoe. Wingtips are another type of derby that feature an exaggerated, almost wing-like tip design. Bluchers are similar to derbies but typically have a more relaxed, open lacing system. All of these shoe designs can be suitable for formal occasions and can provide a stylish, sophisticated look.
