Abstract: An athletic system for monitoring the condition of a wearable athletic device includes the wearable athletic device, first and second input parameters, a computer readable memory, and a microprocessor. At least one of the parameters may be provided a measurement device that may also be part of the athletic system or may be separate therefrom. The first parameter comprises at least one of an event count and a travel distance, while the second parameter comprises at least one of an athletic footwear device identifier, a physical property of the athletic footwear device, a physiological condition, an environmental condition, an event rate, a velocity, and an acceleration. The computer readable memory contains instructions for calculating a condition of the athletic footwear device. The microprocessor is configured to perform the instructions in order to calculate the condition of the athletic footwear device, the calculation being based at least in part on the parameters.
