MK MICHEL KLEIN boots. My mother isn't going to wear these, so I'm selling them. It seems like she may have worn them once. Color: Black Model number: 6892-6213 Heel height: 5.0-5.5cm They are generally clean, but there is some dirt on the soles (see photo ④). They have an air cushion in the heel, making them designed to reduce stress on the feet.
