I bought the Black kit and put it on my 8" side-zip boots and they work VERY WELL. The elasticity makes the boots go on a bit easier while keeping them more consistently snug than the regular laces. They look like they'll be too short for boots, but they are just long enough. I will say that I needed to knot them after putting the slide lock on because it didn't hold that well. I wish I could submit a photo.
