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.
