Using fabric cut into 6-7 cm strips, I sew them with a sewing machine, turn them inside out, and make them into cords to weave into zori sandals. Therefore, there are no frayed edges, resulting in a clean finish. Also, these zori sandals are thick and have excellent cushioning. Furthermore, a great feature of these zori sandals 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 zori sandals" all year round, in spring, summer, autumn, and winter.
