Abstract

A lace (200) for a shoe (C), consisting of an elongate elastic band (2) made entirely of silicone, said band having elastic properties according to which, when at least one segment of said band is selected, said segment having a constant cross-section and a rest length of 5.0 centimetres, when said segment is stretched to a stretched length of 10.0 centimetres and then released, said segment contracts and reaches a first released length of between 5.6 and 7.0 centimetres after a first period of between 0.1 and 1 second after the release, and reaches a second released length of between 5.0 and 5.6 centimetres after a second period of between 15 and 25 seconds after the release. The invention is particularly applicable in the field of sports shoes, and in particular running shoes, to prevent any compression and thus allow good blood circulation while holding the foot comfortably.
