摘要

The footwear has stitching to hold the upper (3) at the sole (1), with openings for the stitching thread (9) to pass through. The edges of the upper and its lining (5) are coated with an adhesive (4,6) towards the sole, which can be activated by heat. A thermoplastic sealing strip (7) is at the lining towards the sole, to be fused with the upper, the stitching thread and the lining.
