Here is a pair of boot cuffs I crocheted. They are 7" x 16" of brown with off white trim. 34 rows of double crochet. First row just double crochet then added button holes and 1/2 row for buttons at the end. The off white trim was 2 rows. the last row I added picots.
. These cuffs are a gift and not made for these boots, but I think you can get the idea.
