Abstract
Laces for shoes, sneakers, or other wearing apparel that adjust easily, but stay tied. In one embodiment, the novel design is a flat lace having an upper and lower surface made from different materials. The surfaces have a relatively low coefficient of friction with respect to a shoe's eyelets. Upon being tied, the surfaces have a high coefficient of friction when they are in contact with one another. An alternative design includes a brush-like array of tiny fibers protruding from the lace surface. Another embodiment consists of a middle portion having material properties different from its end portions. An alternative design has two sets of opposing sides with different material properties. The inventive designs minimize the possibility of laces coming untied.
