Total length is approximately 27cm. It's woven tightly with smooth cord. Because it's woven finely, it has thickness and fits softly to the soles of your feet, providing comfort. The arch of the foot is also woven in. Cloth zori (sandals) will gradually flatten out as you wear them, so the size is generally okay. The space between the toes is designed to be comfortable, so it won't hurt. The core of the thong is made of PP rope split and wrapped in cloth, making it easy to wear. *Reinforcement cord 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 it for a long time. Thank you for viewing. *Delivery will be via Nekopos, one pair at a time.
