a sole integrated into the shoe;
a connection mechanism attached to an underside of the sole, wherein the connection mechanism is shaped to connect the sole to a pedal;
a pressure sensor comprising a first plate and a second plate spaced apart from the first plate to form a capacitor, wherein the pressure sensor is incorporated within the sole of the shoe that senses a force exerted on the pedal when the shoe is connected to the pedal through the connection mechanism, wherein the first plate is located above the second plate, a baseline distance between the first plate and the second plate representing a distance between the first plate and the second plate in the absence of upward and downward forces, and the pressure sensor determines an upward force based on if the distance between the first plate and the second plate is greater than the baseline distance and the pressure sensor determines a downward force if the distance between the first plate and the second plate is less than the baseline distance; and

Abstract
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.
