1. A sensor system comprising:

  • an insert member configured to be inserted into a foot-receiving chamber of an article of footwear, the insert member comprising a first layer and a second layer;

    a port connected to the insert and configured for communication with an electronic module;

    a pathway providing electrical communication between the first layer and the second layer;

    a plurality of sensors formed on the insert member, each sensor comprising a first contact located on the first layer and a second contact located on the second layer, the second contact being generally aligned with the first contact, wherein the sensors are each configured such that pressure on the insert causes increased engagement between the first and second contacts to change a resistance of the sensor;

    a plurality of leads located on the first layer and the second layer, the leads connecting the first contacts, the second contacts, the pathway, and the port;

    a first resistor located on the first layer and connected to at least one of leads; and

    a second resistor located on the second layer and connected at least one of the leads,wherein the port, the pathway, the sensors, the leads, and the first and second resistors form a circuit on the insert member, the circuit configured to have a voltage applied between a first terminal and a ground located at the port, and wherein the first and second resistors are arranged in parallel between the first terminal and the ground, andwherein the insert member further comprises a spacer layer located between the first and second layers, the spacer layer having holes aligned with the sensors to permit engagement of the first and second contacts of each sensor through the spacer layer.
