Abstract
A lace structure includes a plurality of weaving threads and a plurality of resilient threads which are interlaced in a lengthwise direction to form an elongate lace which defines a plurality of first sections and a plurality of second sections arranged in an alternating manner. Each of the second sections of the lace has a weaving density greater than and a width smaller than that of each of the first sections. In such a manner, each of the first sections of the lace has a wide face with a low density, and each of the second sections of the lace has a narrow face with a high density. Thus, each of the first sections of the lace has an elasticity greater than that of each of the second sections, so that the lace has a stepwise elastic function.
