Stylish high-heeled design with zipper, black SNEAKER HEELS, and a tread sole. 24-24.5cm L size - Color: Black - Design: With zipper - Heel height: Approximately 9cm - Material: Synthetic fiber - Sole type: Tread sole Thank you for viewing. They are comfortable to walk in, like sneakers, and have high cushioning, so your feet won't hurt. Those with high insteps can also adjust them with the zipper. The zipper is in the center, making them easy to put on and take off. Used about twice, and I used insoles, so they are in good condition and can still be worn.
