1. System for the determination of movement characteristics in running disciplines, such as strides length, running speed or the like, with shoes, especially athletic shoes, comprising:

  • (a) first and second shoes;

    (b) first sensor means, in said first shoe, for responding to lifting off of the first shoe from the ground;

    (c) second sensor means, in said second shoe, for responding to contacting of the second shoe with the ground;

    (d) first transmitter means, in said first shoe, for radiating a first signal, said first transmitter means being triggerable by a response from the first sensor means;

    (e) second transmitter means, in said second shoe, for radiating second and third signals, said second transmitter means being triggerable as a result of a response from the second sensor means;

    (f) first receiver means, in said first shoe, for receiving the third signal and for causing said first transmitter means to radiate a fourth signal in response to receipt of said third signal;

    (g) an evaluating arrangement that is operable for determining the movement characteristics of a user wearing the shoes based upon the first, second and fourth signals according to signal timing and origin; and

    (h) second receiver means, positionally spaced from said shoes, and for receiving the first, second and fourth signals, differentiating these signals and, after differentiation, feeding these signals to said evaluating arrangement.
