Slippers have been around for centuries, with the earliest known examples dating back to the 12th century. These early slippers were made of leather and were often lined with fur or wool to keep feet warm. Over time, slippers became more elaborate and were often decorated with embroidery, beads, or other embellishments. Today, slippers are made from a variety of materials, including leather, fabric, and rubber, and come in a wide range of styles to suit different tastes and needs.
