These are lightweight, quick-drying waraji-style zori (Japanese sandals) made by wrapping a nylon core with recycled kimono fabric. They are new as zori. The fabric is from a tsumugi kimono. Size L, recommended for those who wear 24-24.5cm shoes. Hand wash and put in a net for spin-drying, or machine wash in a net on the delicate cycle. Please wash separately as color may run. If the thong loosens or feels tight after wearing for a while, try untying and retying the thong on the underside. Please understand that these are handmade and not perfect. Please refrain from purchasing if you have a dog allergy.
