Systems and methods of monitoring a running step and signaling the runner when a correction is desired. In one aspect, the portion of the foot that contacts the ground first is monitored to determine if a correction is desired. To monitor the running step, a step analyzing apparatus can be used that is positioned within a shoe. The step analyzing apparatus can include sensors that are positioned at the midfoot and the heal when the apparatus is within the shoe. To signal the runner, an indicator can be used that is positioned within the shoe or outside the shoe. The step analyzing apparatus can also be used in a ski boot to monitor proper ski form. Running cadence can also be monitored to determine if a correction is desired.
