Black open-toe wedge heel mules with ankle straps for comfortable wear. - Color: Black - Design: Open toe - Style: Wedge heel - Strap type: Ankle strap Thank you for viewing. Color: Black系 (Black-based) Heel height: 7.5cm Size is marked as 36, which is a small size, approximately 22.5cm to 23cm. I purchased these at a specialty store several years ago. I believe they are made of cowhide. I have worn them about 10 times and then stored them. There are a few small scratches if you look closely, so please understand that they are used. However, I think they are in good condition. I am selling them now to declutter. Thank you.
