It's made of stretchy fabric, like a black jersey. The heels are about 5 centimeters high, and I think they're easy to walk in. I bought them at a store in Tokyo a few years ago for over 100,000 yen. I only wore them a little bit in the store, which had carpet, so they're in beautiful condition. The seller can no longer wear stiletto heels, so I'm selling them. They had a very lovely design and were popular. Please refrain from purchasing if you are overly concerned about details.
