The BIRKENSTOCK Zermatt is our first slipper with a removable sole, allowing you to choose between three different soles: the standard sole, the soft sole, and the sheepskin sole. All three insoles can be ordered separately, making it perfect for year-round wear. This basic version features our Shearling sole and lining to keep your feet warm in colder temperatures. The upper is crafted from soft wool felt. Our (f) model is designed for narrow widths, while our (m) model offers a regular fit. It boasts an anatomical cork-latex sole (sheepskin sole), a wool felt upper, a shearling sole lining, and a latex sole. Details include a clog design with an extended shaft, decorative stitching, and a decorative rivet. The sole is "Made in Germany".
