The method comprises the following steps: (a) gathering the sheet material by parallel stitching two elastic strips on the opposite side edge portions respectively of the sheet; (b) folding the sheet in two along its longitudinal center line, so as to bring the two gathered side edge portions in respective abutting register; (c) with an ultrasonic press, weakening narrow sections of the sheet transversely to the axis of the longitudinal center line, at regular intervals, and concurrently cross-bonding the sheet along both edge portions defined by each one of the weakened narrow sections of the sheet; and (d) detaching the desired segment of sheet of material along the line of bonding, for any one overshoe. Also, the products obtained by the above-described method.
