Edea laces made of carded, flat tubular polyester making them tangle resistant and extra strong. Edea added a finishing touch of style to these laces with one Swarovski crystal on each lace. Laces should be changed as soon as they lose their texture and elasticity as this will mean they come loose more often. On average, laces need to be replaced every 3-4 months. Color: available only in white. Lace size: 200-220-240-260-280 Boot size: 185-210, 215-230, 235-250, 255-290, 295-310
