1. A method for gait analysis, comprising:

  • fitting a shoe insert in a shoe, the shoe insert having force-sensing sensors disposed at predetermined locations, each sensor providing a respective electrical output signal;

    having a subject wear the shoe with insert while walking;

    obtaining samples of the electrical output signals of the sensors during the subject'"'"'s walking; and

    from the samples of the sensor output signals, calculating a gait line being represented by a series of points in a two-dimensional space corresponding to a sensing aperture extending across the shoe insert, each point being calculated as a spatially-weighted average of respective samples of the sensor information signals so as to indicate at least a first-order moment of the forces applied to the shoe insert by the subject during the gait analysis process.
