These zori are made from natural igusa (rush grass), a natural material, and have a very gentle and soft feel on the feet. The thong goes between the big toe and the second toe, making them less likely to cause you to trip, and I think they are easier to wear than regular zori or geta (wooden clogs). I have kept them stored at home. The size is 18cm overall when measured with a measuring tape, and I think they would fit a child who wears about 15cm shoes. How about these for your child to wear with a yukata (summer kimono) or for their everyday foot health? ✾
