1. A method of generating route data corresponding to a route traversed by a user wearing a shoe, the method comprising:
generating three-axis direction data in response to movement of the shoe as the user traverses the route with a magnetometer mounted on the shoe;
determining two-axis calibrated direction data based on the three-axis direction data after the user traverses the route with a controller operably connected to the magnetometer, the two-axis calibrated direction data corresponding to an orientation of the shoe;
generating acceleration data with an accelerometer mounted on the shoe as the user traverses the route; and
determining route data corresponding to the route by processing the acceleration data and the two-axis calibrated direction data with the controller.
