Abstract
The invention provides a shoe having a built-in, electronic wear indicator device capable of signaling (a) extent of shoe sole wear, (b) loss of ability to cushion and absorb shock, and (c) a need to replace the shoe. The wear indicator device comprises (a) a sensor and microprocessor which can measure and report the use history of the shoe, (b) a wear indicator display which shows the consumer the current point in the shoe's life cycle and (c) a power source. The wear indicator device is installed between the midsole and outsole during the manufacturing process and is therefore, built-in and unobtrusive to the user.
