After having received my shoelaces the first thing I noticed is their rich color. A deep vibrant hue is important for colored laces. It's what you purchase them for. They stand out. When I unrolled them it was evident that they were quite hefty and would wear well with my Indy boots. When I laced the boots and tightened them to my feet I felt no hesitation with drawing the laces tighter, without fear of breakage. I suspect the laces will provide years of wear and use before needing replacing.
