The fabric is cut into strips 6-7cm wide, sewn with a sewing machine, turned inside out, and made into a string. Therefore, there are no frayed edges, making them neat and tidy. Also, these cloth zori (sandals) are thick and have excellent cushioning. Furthermore, a great feature of cloth zori is that your feet are always "smooth and dry!" and "never stuffy!" If you feel they are "damp!", put them in a laundry net and wash them. The fabric will become "plump" again, and the comfort will be "revived! Revived!" Please enjoy these "extremely durable cloth zori" in spring, summer, autumn, and winter. Yamashina Kobo
