Abstract: A foot mounted apparatus for measuring one or more locomotive performance parameters of a person is disclosed. Such locomotive performance parameters preferably include user vertical leap time, user vertical jump distance, user walking or running speed, user trip distance traveled, and accumulated total lifetime distance traveled by the apparatus. It is preferred that the apparatus include all of the structures of an athletic shoe such as a sole, upper, tongue, and lace. Four membrane switches are located in the sole of the footwear: a pair of membrane switches is positioned under the ball of the user's foot and a pair of membrane switches is positioned under the heel of the user's foot. The membrane switches sense the compressive pressure of the foot on the sole and detect when the foot leaves and contacts the underlying surface. A microprocessor calculates a performance parameter for the person based upon the elapsed time between the foot push off and the foot strike.
