I'm not certain, but I think I bought these about 6 years ago for around 25,000 yen. I've only worn them a few times and have been storing them at home, hoping to wear them someday. I believe they are made of high-quality leather, with a nice sheen and a soft feel. They have heels, but they are easy to wear. I'm a novice at measuring, but from the heel up, they are 35 cm. My own foot measurements are: calf 33 cm, below the knee 31 cm, and ankle 21 cm, and they fit perfectly.
