Abstract
A slip-proof shoelace being characterized in that: a slip-proof member with a larger coefficient of friction (such as made of silicone, rubber or chemical plastic weaving fiber) is provided on a suitable length extending from each of two ends toward the other end of the shoelace. The slip-proof member can be an elastic sleeve with a smooth surface or a plurality of annular ribs, helical ribs or granules, extending from an end toward the other end of the shoelace, so that the shoelace forms an engaging action at the tying up area, and by the feature of having a larger coefficient of friction, the shoelace can be prevented from loosening and dropping.
