These chunky crochet boot cuffs are given in one size, but can easily be adjusted for other sizes as well.
Wear them with knee high or ankle boots for an extra layer of warmth. Plus, they are nice and long, so you can fold them over your boots if you like.
I used a chunky yarn, which makes them quick to crochet, but choose any other yarn you like and make adjustments as needed for the size you need.
