An Oxford shoe is characterized by shoelace eyelets tabs that are attached under the vamp, a feature termed “closed lacing”. This contrasts with Derbys, or bluchers, which have shoelace eyelets attached to the top of the vamp. Originally, Oxfords were plain, formal shoes, made of leather, but they evolved into a range of styles suitable for formal, uniform, or casual wear. On the basis of function and the dictates of fashion, Oxfords are now made from a variety of materials, including calf leather, faux and genuine patent leather, suede, and canvas.
