Abstract

An article of footwear can include a ferromagnetic body disposed in the article, and a magnetometer to measure a strength or direction of a magnetic field that is influenced by a position of the ferromagnetic body. One of the ferromagnetic body and the magnetometer can be configured to move relative to the other one of the ferromagnetic body and the magnetometer, for example according to movement of a foot in the article. In an example, the ferromagnetic body is disposed in a compressible insole and the ferromagnetic body moves in response to compression or relaxation of the insole. The magnetometer can be disposed in a platform or sole portion of the article that is relatively stationary compared to the ferromagnetic body. Rate of change information about the magnetic field can be used to control article functions or to provide information about a foot strike or step rate.
