Size: US5.5 (approximately 22.5-23cm) *I usually wear 23-23.5cm in Japan, but I remember these felt a bit tight. I've disposed of the box, so the product details are unknown. The soles have metal in them. I purchased these in the US about 20 years ago and used them for about a year of horseback riding lessons. After that, I stored them in a shoe closet and occasionally cleaned them with a cleaner. These are items that have been stored at home for a very long time, so please understand this before purchasing. *No pets, no smokers.
