The size isn't indicated, so it's unclear, but I usually wear shoes around 23cm. I tend to buy boots around 24cm to accommodate thick socks, so please use that as a rough guide. I bought these 5-6 years ago and wore them frequently the first year, but in recent years I've just been taking them out and putting them away, so I haven't had many chances to wear them. I'm putting them up for sale. Despite the years, there's no deterioration inside or out, and they still seem to be in good condition. I hope someone who needs them will use them.
