ABSTRACT:
A device and method are provided for determining the wear of a sole of a shoe. The device includes first and second sensors receivable in the sole of the shoe. The sensors are axially spaced and generate signals in response to corresponding impact forces acting thereon. A control circuit is connectable to the first and second sensors. The control circuit compares the difference between the first and second signals to a threshold and generates an alert signal in response to the difference between the first and second signal meeting the threshold.
