Gorgeous and soft natural sheepskin bootie slippers that will instantly warm your full body on cold days. These are the ultimate lounge booties, perfect for a lazy weekend morning. If you are looking for natural (not from synthetic fiber) warmth, these are the perfect accessory. 

These booties are especially great for those who love the natural movement of their feet, as there is no rubber or plastic sole. Made from 100% sheepskin, using the leather as the sole with extra fur padding inside. I personally appreciate this flexibility within a slipper, allowing my feet to be relaxed in their natural movement and flow when I’m lounging on a couch or bed.
