These platform sandals offer a style-enhancing silhouette. The instep and heel straps are all Velcro, making adjustments and putting them on and taking them off a breeze. These sandals are designed for a relaxed fit, with thick straps that wrap around the entire foot. The underside is made of nylon, making them perfect for everyday wear. The basic, single-tone colors are also appealing. Thank you for viewing. I have only worn them once.
