Shoe seam along heel - joints two parts of upper using two grooves parallel to edges of upper parts

摘要

The shoe consists of two upper parts (1, 2) which are sewn together by a seam at the heel after being bent over along the edge. The two upper parts are made thinner near the seam by means of a groove (9, 10) running parallel to the edge (7, 8) of the two parts (1, 2) of the upper. The joining seam (13) is embedded in the grooves (9, 10). The distance (A) between the edge (7, 8) of the upper parts (1, 2) and the groove (9, 10) is less than the width (B) of the groove (9, 10).
