Total length is approximately 22.5cm. These are cute red zori (Japanese sandals). They are carefully and tightly woven, making them thick and comfortably soft against the soles of your feet. The arch of the foot has also been additionally woven. Cloth zori tend to flatten out with wear, so the size can be approximate. They are made to fit comfortably between the toes, so they won't hurt. The core of the thong is also made by splitting PP rope and wrapping it with cloth, making them easy to wear. *A reinforcement string is included to use if the thong loosens with continued wear. All materials are new. Wash by hand or in a laundry net. I think you can use them for a long time. Thank you for looking. *Delivery will be via Nekopos, one pair at a time.
