Over ten years ago I bought a pair of classic Roots boots with some gift certificates I'd won at work. It was definitely not about fashion — I was just sick of having to worry about falling down on Toronto's icy sidewalks every winter.
To my great surprise, the boots have held up, although they're no longer as waterproof as they used to be. Usually at the most I get two seasons out of a pair of winter boots.
The one thing that does keep wearing out on these are the bootlaces. For years I would buy replacement laces, but this was a bigger deal than it sounds because for some reason it's hard to find replacement laces for boots (shoes are easy, but not boots).
I finally remembered reading about I-cord laces in an old copy of Interweave Knits, grabbed my Inox I-cord maker, and cranked off some of my own.
Turns out I-cord makes great laces for hiking-style boots. If you leave the tails on the ends of the I-cord, it's easy to pull the laces through the grommits, and if you use leftover variegated sock yarn like I did, you can get a nice funky look going:
Just make sure to take into account that the laces will stretch a little once you use them a few times. I couldn't get the laces comfortably into the top grommits when I first made the laces, but now they not only fit, but they're plenty left over for tying them up.
