The Planegg is a comfortable, round, leather-lined slipper. Available in a variety of colors. Available in sizes 36-42 (EU.) The outer fabric is made of 100% cotton, and the sole is made of synthetic material. The slipper’s easy, slip-on opening makes it very easy to slide on or off. The summery Planegg sipper features a woman sitting on a bench next to an ice cream cart.
