Systems and methods for a self-contained shoe insole device to monitor biomechanics and motion are disclosed. The systems and methods allow monitoring for orthopedic diagnostics, fitness tracking, and social/gaming activities using a shoe insole device with multiple sensor locations for pressure, acceleration, rotation rate, all forms of inertial data in three axes, position/location, heart rate, and other physical attributes. The shoe insole device can include a plurality of layers, with one layer containing a plurality of sensors, and an electronics component for collecting, reading, storing and transmitting the sensor data. The shoe insole device can wirelessly connect with external computing devices for monitoring and feedback directly to the user or a health care or fitness training professional, or across multiple users in a social or gaming situation. The system can further be provided for monitoring and tracking physical activity and enable a variety of interactions based upon the collected data.
