The invention relates to a shoe (10) with a tongue (12) and laces comprising: (a) retainer means (16; 46); (b) said tongue (12) having a front face (28) and a rear face (30); (c) said retainer means (16; 46) being affixed to the front face (28) of said tongue (12); (d) a slot (26) extending entirely through the front face (28) and the rear face (30) of said tongue (12), said slot (26) being displaced from said retainer means (16; 46) sufficiently to permit a knot to be tied therebetween; (e) an elastic band (18) having a fixed end (24) and a distal end (20), said fixed end (24) being fixed to the rear face (30) of said tongue (12) and said distal end (20) being arranged for extending through said slot (26) for engagement with said retainer means (16; 46); and (f) said elastic band (18) being configured to extend over a tied knot of the laces, to interengage with said retainer means (16; 46), and to grasp the knot from opposed sides with sufficient tension to impede the knot from becoming untied. In one embodiment the retainer means comprises a hook member (16). Alternatively the retainer means can be one part of a separable fastener, the complementary part of which is carried by the distal end of the elastic band. |
