Abstract: An insole (102) for a shoe is provided, having a display surface (116), preferably disposed on an insert, for the display of information when the insole is in place in a shoe. A shoe (10), for example a sports shoe, is also provided having a receiver disposed on its external surface. The receiver retains an insert having a display surface, visible when the shoe is being worn and adapted for the display of information. The display surface may carry a brand or other design and/or emit light or sound by means of a suitable emission device. An accessory for a shoe comprises a mount for securing to a shoe, the mount having a display surface adapted to be visible when the shoe is being worn. The mount preferably holds an insert of the kind mentioned above.

Abstract: A shoe has a sole, at least a portion of the sole of the shoe comprising a compressible material, the material being such that the application of a pressure above a threshold pressure causes the electrical conductivity of the material to change. There is also provided a shoe comprising a sole; a display means operable by the wearer of the shoe to provide a display on the exterior surface of the shoe; wherein the sole of the shoe comprises a compressible material, the material being such that the application of pressure causes the electrical conductivity of the material to change, whereby the display means may be controlled by the application of pressure to the compressible material in the sole of the shoe. An insole for use in a shoe is also disclosed, the insole comprising a compressible material, the material being such that the application of a pressure above a threshold pressure causes the electrical conductivity of the material to change.
