Each Barne slipper is unique and handmade from repurposed Kilim rugs. Our slippers are primarily designed to be used indoors! While the slippers are intended for indoor use, we recommend adding a sole for extra protection and durability if you wish to wear them outdoors. The size is EU true to size, and we recommend choosing your usual size. Keep in mind that the slippers may give slightly and offer a bit more space as they adapt to your feet with wear. (Please note that for deliveries outside the EU, customs duties and import fees may be charged by your local customs office)
