EUC Guess black over knee boots. Sz 6-1/2.

Guess black over knee boots w 4-1/4” heels. Inner zipper in ankle area. Ties at top behind knee area. Approximately 6-1/2 in calf area to top. Feels like some type of poly interior. Outer is some sort of fabric that resembles suede. Definitely not suede as their is no leather fragrance. I cannot find any content label, but it is definitely Manmade.
