1. A device for determining the wear of a sole of a shoe, comprising:
- a first sensor receivable in the sole of the shoe, the first sensor generating a first signal in response to a first impact force thereon;
a second sensor receivable in the sole of the shoe, the second sensor generating a second signal in response to a second impact force thereon; and
a control circuit connectable to the first and second sensors, the control circuit generating an alert signal in response to the first and second signals.

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.

8. A device for determining the wear of a sole of a shoe, comprising:
-
a first pressure sensor receivable in the sole of the shoe, the first sensor generating a first signal that is proportional to a first impact force acting thereon;
a second pressure sensor receivable in the sole of the shoe at a location axially spaced from the first pressure sensor, the second sensor generating a second signal that is proportional to a second impact force acting thereon; and
a control circuit connectable to the first and second pressure sensors, the control circuit comparing the difference between the first and second signals to a threshold and generating an alert signal in response to the difference between the first and second signal meeting the threshold. - View Dependent Claims (13)

14. A method for measuring the wear of a sole of a shoe, comprising the steps:
-
measuring an impact force exerted on a first portion of the shoe;
measuring an impact force exerted on a second portion of the shoe;
comparing the impact force exerted on the first portion of the shoe and the impact force exerted on the second portion of the shoe; and
generating an alert signal if the difference between the impact force exerted on the first portion of the shoe and the impact force exerted on the second portion of the shoe meets a threshold. - View Dependent Claims (15, 16, 17, 18, 19, 20)
