These waraji-style sandals are made from yukata fabric, woven around a nylon core, making them lightweight and quick-drying. Although made from recycled fabric, they are new as sandals. Size L, recommended for those with feet around 24-24.5cm. Hand wash and put in a net for spin-drying, or machine wash in a net on the delicate cycle. Wash separately as color may run. If they feel tight or loose while wearing, untie and retie the thong on the underside. Please understand that these are handmade and not perfect. Please refrain from purchasing if you have a dog allergy.
