1. A sensor system comprising:
a flexible insert member configured to be connected to a sole structure of an article of footwear;
a port connected to the insert member and configured for communication;
a plurality of sensors connected to the insert member, each sensor comprising a strip of a sensor material that is electrically connected to the port, wherein a first plurality of the strips of the sensor material extend from a midfoot region to a forefoot region of the insert member, wherein the first plurality of strips define a plurality of different lengths, and wherein the sensor material of each sensor is a piezoelectric material configured to generate a voltage when deformed; and
an electronic module connected to the port, wherein the electronic module is configured for collecting data from the sensors based on voltage generated by the piezoelectric material and for communication with an external device, wherein the electronic module is further configured for determining a degree of flexing of the forefoot region of the insert member based on a number of the first plurality of strips that are deformed.
