Abstract
A slip resistant shoe lace and a method to make same. A slip resistant shoe lace is provided by weaving strands having a conventional frictional coefficient with at least one strand having a higher frictional coefficiency, where the high-friction strands do not extend beyond the outer perimeter of the lace. The high-friction strands can be made by impregnating conventional strands with friction-enhancing substances such as resin or rubber, by using a unitary strand made of material such as rubber or soft plastic, or by using strands with grooves or serrations formed on its outside surface.
