Black knee high boots sz 8.5

NLYA Mitchell Laced Boot. Black knee high boots I bought from Nordstrom last year. They have a six inch heel and a slight platform, I'd say less than an inch. 20 inches tall from floor to top. Have a zipper on the inner side. They look like real leather, but I'm pretty sure they are not. I wore them once and they are awesome boots, but no matter what I do, I'm just not cut out to wear 6 inch heels 😭. The tag say over the knee, but it's more to the bottom of the knee
