These are vintage 1970s leather platform sandals, likely made in Brazil. Run about a half size small. I normally wear a 6-6.5. Product Details Style: Bohemian-style open-toe slingback sandals with a high-heeled wooden platform. Material: The upper is made of warm reddish-brown leather with woven or basket-weave detailing and top-stitched accents. Features: They include buckled ankle straps and a wooden heel, a common design element from the 1970s. Identifying Marks: The numbers seen on the inner strap (17147 and 78) are likely model or batch numbers rather than a widely recognized brand logo.
