<p>The reinforcing edging for shoes has a body, made of rigid or semi-rigid material e.g. synthetic rubber or polypropylene surrounding the heel at the back of the shoe. Around the body there is an extra thickness (6) on the exterior, at the base and covering part of its height. The extra thickness is formed tangentially to the body of the edging at its upper part, and covers at least half the total height of the body.</p> |
