1. A system for analyzing athletic activity, comprising:

  • an article of footwear including a sensor system comprising a plurality of force sensors engaged with the article of footwear and configured to sense force exerted by a foot of a user, an electronic module contained within the article of footwear, and a plurality of sensor leads connecting the force sensors to the electronic module, wherein the electronic module is configured for collecting data based on force input from the force sensors and for transmitting the data, and wherein the force sensors include at least one force sensor in each of a forefoot portion, a midfoot portion, and a heel portion of the article of footwear; and

    an electronic device in communication with the electronic module, wherein the electronic device includes a processor configured to perform;

    receiving the data from the electronic module;

    comparing the data to a footstrike template corresponding to a first footstrike pattern to determine whether a deviation from the footstrike template exists, wherein the deviation is determined to exist if a degree of deviation from the footstrike template is determined to exceed a predetermined threshold, and wherein the predetermined threshold includes both a force threshold and a timing threshold, wherein the timing threshold relates to at least one of a desired sequence of impacts and a desired contact time for the force sensors, such that the deviation is determined to exist if the force threshold of the predetermined threshold is exceeded and if the timing threshold of the predetermined threshold is exceeded; and

    generating an indication to the user when the deviation from the first footstrike pattern is determined to exist, wherein the indication further includes the degree of deviation from the footstrike template for each of the force sensors.
