I'm not sure of the exact size because it's missing. It's the same length as the 21.5cm insole in the image, so it's probably 21.5cm, but the width is narrow, so I'm not sure. I think it would fit better if your foot size is smaller than 21.5cm. Only for those who understand the size. The Moonstar insole in the image is not included. ⚠ There are stains, fraying, scratches, wear, and cuts. Please refrain from purchasing if you are concerned about these. ⚠ For shipping, I will pack the item in a Yu-Packet Plus dedicated box, compressing any protruding parts (heel, top, etc.). Please be aware of this. The shipping method may change. ⚠ It may take some time for delivery. If you are in a hurry, please consult before purchasing. Please only transact if you understand. If you have any questions, please ask before purchasing.
