Abstract
Footwear (1) adapted to enhance the visibilty of the wearer contains a light source (12), a power source (14), circuitry (15, 16, 17) to connect the power source (14) to the light source (12) , and a pressure switch (18) disposed in the sole (5) of the footwear (1) between the wearer's foot and the ground and adapted to turn the light source (12) off when the wearer's foot is on the ground, and hence static, thereby conserving the power source (14), and to switch the light source (12) on when the wearer's foot is off the ground, and usually moving, thereby providing enhanced visibility of the footwear (1) and its wearer.
