This summer, I spotted a set of Hickies shoelace replacements in an airport store while killing time between flights. I was attracted to them because they were safety orange, which is my favorite color. They're marketed as elasticated "lacing systems" for kids who don't want to hassle with tying their shoes, but my wife pointed out that they'd probably look cool in my old black boots. She was entirely correct, and they've also greatly eased the process of slipping the boots off and on at airport checkpoints (and when I get home for the night). They're easy to install, come in a variety of hot colors, and they look damned cool.
