If you look at the earliest huaraches, and if you look at sandals made in other indigenous cultures in Australia and in Africa, you'll find that they are made with leather.
Sometimes they are all leather, with a leather base and leather upper. Some have a woven leather upper for a traditional Mexican huarache or a leather foot bed and leather straps or laces for the sandals worn by the Tarahumara.
