Size: Length 25cm, Width 10cm These cloth zori (Japanese sandals) are durable and cushioned, as a 3cm wide core cord is woven into the string used to make them and then hand-sewn. They feel good on bare feet and are warm to wear with toe-socks. Washable: First, soak in water, then scrub with a sponge or put in a laundry net and wash in the washing machine. Dry for 2-3 days. They will widen and loosen slightly with wear. If the thong loosens, tighten the cord on the underside.
