The Birkenstock Yara stands out with its curvy narrow strap that gives the sandal a feminine touch. The heelless sandal with an ankle strap combines optimum grip and comfort with a light and svelte appearance. The upper is made from extra thick, oiled nubuck leather with an open-selvage finish Used angry condition. I only use them for at least two weeks. Great handle for traveling super lightweight and very packable. Super comfortable.
