Thank you for viewing. These are handmade cloth zori (Japanese sandals). Color: Navy Size: 23 cm Please allow for slight variations as measurements are approximate. Zori are currently being reconsidered for their health benefits and are said to be good for bunions, ingrown toenails, and dieting. If they get dirty, you can wash them. Put them in a laundry net and wash them in the washing machine. The design allows you to retie the thong from the back if it becomes loose. Made in a smoke-free and pet-free environment. Please refrain from purchasing if you are concerned about minor details, as these are handmade. Thank you very much.
