Size: 23cm Fits those with feet 23-24.5cm Width: 8.5cm Uses 10mm PP rope Carefully woven with genuine silk. Since genuine silk is a natural material, it has excellent moisturizing and breathability properties, which will make your soles beautiful and comfortable to wear. Because they are zori sandals, the size can be used regardless of slight variations. Cloth zori sandals also stimulate the acupressure points on your feet and can be expected to strengthen the muscles in your toes and soles, making them feel great. They may feel tight at first, but they will loosen up and conform to your feet after a while. They can be washed in a washing machine using a laundry net. Please understand that there may be some slight distortions and differences between the left and right sides due to being handmade.
