The last time I purchased some laces for my older boots, I bought Core by Derby Laces. They are sold online, and I like them better than most of the skate-branded laces available at pro shops.
At that time, I lamented that they didn't have slate gray laces. I sometimes have a hard time seeing black laces against black boots. (Yeah, I know, but I don't wear my glasses into the rink because a) I can't skate with them because they fog-up, or tears get splashed onto them, or b) I have to store them in the skate bag where I have been known to place my skates on top of them.)
Previously, I had purchased some other colors besides black to try, but didn't find them to my liking. Without gray available, I stuck with basic black.
Well, guess what! They now have gray!
That's perfect! I can actually see the laces for a change. Plus, they will go with my gray hair!
Sometimes it's the little things.
