The delay (t<d<i<r<.) measured from the rear shoe (2) of a signal (dir.) emitted when the front shoe (1) is placed on the ground is transferred in time conformance to the first shoe (1) and from the first shoe, the counter statuses of the two counters (Z1 and Z2) are sent to a computer unit at high frequency (Fig. 3)de608006621patent1986-3617591
