⚠️ I have lost the box, so I cannot confirm the size. I believe it is around XS (20-22cm), but please consider this as a guideline only. I purchased this a while ago and only tried it on once. However, it was a little different from what I imagined, so I stored it without using it afterwards. Also, the design is quite tight, and I found it difficult to put on, even though my foot size is about 22cm. Please note that the fit may vary from person to person. ⚠️ Please refrain from purchasing if you are concerned about minor details due to the item being stored by a private individual, or if you are unsure about the size.
