Instant purchase is welcome. I bought these at a shoe store last year and wore them once, so they are almost undamaged and in good condition. I'm selling them because I no longer wear shoes with heels. They are made of stretchy faux suede. These are black platform knee-high boots with a side zipper for easy wear. - Color: Black - Style: Knee-high boots - Heel height: Platform heel, 8 cm - Zipper: Side zipper - Size: M - Length: 60 cm (including heel) I wore these, and I usually wear a size 24 cm. Thank you for looking.
