The style of shoe does have much to do with dancing but also fitting if with the overall look of the outfit. With back tie in the past the lighting would have been dimmer and a greater appreciation was for the play on textures. You suit a fine wool. The lapels covered in silk (be it grosgrain or plain). Silk stockings and a delicate shiny shoe. As you can see a brogue shoe amongst that doesn't follow the play of textures. It is too textured. The same as wearing brogues with baggy jeans look too delicate for the outfit. Everything has it's place.

Black tie is all about simplicity of textures.
