Product title: Rafe Women's 102658 Coco Platform Wedge
Product description: This Coco wedge is Rafe's sweet and sexy take on the classic boat shoe, and we absolutely love it! It has a lightly tumbled leather upper with contrast stitching, a cotton rope detail on the vamp, and an adjustable ankle strap that will secure the best possible fit. Wait! We're not finished! We especially can't get enough of the printed, cushioned insole, and the woven jute wedge--combined together they add nothing but personality and fun., Designer Rafe Totengco is a true New Yorker. Originally from the Philippines, he came to New York City to pursue his dream of a career in fashion armed with ambition and his unique design sensibilities. In a city that's all about individuality, Rafe fit right in. In 1994, he produced his first accessories, belts, and watchbands and one year later the first collection of Rafe New York handbags debuted at uptown department store Bergdorf Goodman. Since then, Rafe has become one of the most acclaimed of a new generation of New York designers.
