These are super easy to make. :)
But just to warn you, this is not an actual crochet pattern, I made it up as I went along. So the instructions aren’t the best.
I used a size J hook
First row: Loosely Crochet 17 single crochets
Second row: Skip two stitches and Half Double Crochet in each single Crochet, Single crochet 2 stitches at the end.
Third row: Half Double Crochet into the back loop, across the next row, at the end single crochet 2 stitches (the rest is the same as the Third row)
Continue till you can wrap it around your calf for sizing, to finish take yarn needle and sew the ends together. Make sure it is tight on you (or it will slide).
Then wear! :)
