As Birkenstock's first true slipper, the Zermatt Rivet combines traditional craftsmanship with modern comfort, making it the perfect addition to your indoor footwear collection. The upper is crafted from soft, genuine wool felt, one of the oldest and most durable textile materials known for its natural insulating properties. This material not only provides warmth but also adds a touch of classic style to your everyday wear. Inside, the slippers are fully lined with luxurious shearling, offering unmatched warmth and comfort. The shearling lining is made from high-quality sheep- or lambskin, which is both breathable and temperature-regulating, ensuring your feet stay comfortable no matter the season.
