Abstract
A device, inserted in a running shoe is used to track the accumulation of destructive compression cycles within the shoe and to indicate this information to the user through a series of integrated indicators. The device has an advantage of being able to be placed in any shoe without compromising the construction or performance of the shoe. An additional advantage of the invention is the improved accuracy of the information by improving both the stability and longevity of the sensor system and the ability to distinguish destructive, partially destructive and nondestructive compressions. Another advantage of the invention is the reduction of the cost of construction while achieving a lifetime in excess of the shoe. Yet another advantage of the invention is the user interface, which is contained completely within the device allowing the user to view the information within the shoe.
