A method for distinguishing a foot motion of a user by placing a pedometer at a foot of a user includes the steps of collecting an accelerating data from an accelerometer in a real time manner; filtering the accelerating data via a smoothing filter and a Kalman filter; generating a step data that represents number of steps taken by the user in response to the accelerating data through the smoothing filter; generating an activity data that represents a foot motion of the user in response to the accelerating data through the Kalman filter; and combining the step data and the activity data to form a resulted data that distinguishes the foot motion with step count of the user.

A tensioning system for articles of footwear and articles of apparel is disclosed. The tensioning system includes a tensioning member that is tightened or loosened using a motorized tensioning device for winding and unwinding the tensioning member on a spool. The tensioning system may be used with various sensors to determine how the motorized tensioning device should be controlled.

A monitoring system includes a shoe and a sole integrated into the shoe. The monitoring system also includes a connection mechanism attached to an underside of the sole and is shaped to connect the sole to a pedal. A pressure sensor is incorporated into the shoe that senses a force exerted on the pedal when the shoe is connected to the pedal through the connection mechanism.
