Michael Kors 8.5M black/grey ankle boots, heels

Super sassy zip-in ankle boots with double-buckles. Mixed materials: primarily black patent leather with a grey felt/boiled wool type material in the mid-section of the shoe. Heels are 5 inches, platform is 1.25 inches. Only worn once or twice back in my single days and have held on to them for their aesthetic value in the closet- gorgeous! Purchase price may have been more than $250... I just can't remember and cannot find any reference information online.
