This is a product I urgently purchased at ABC Mart. I bought these because the boots I was wearing during my trip hurt my feet. I only used them for two days. It says size M, but I think it's about 23-23.5cm. Length is 12cm. Heel is 5cm. I bought them because they were easy to wear. 5,900 yen. Please refrain from purchasing if you are sensitive to used items. Thank you very much.
