These stunning slippers are by far the best I have ever owned and are definitely worth paying the extra for. The memory foam bed is so comfortable. They are warm but breathable (an unusual combination). The rubber outsole allows for both outdoor and indoor wear, and the construction is very durable and seamless. I liked my pair (size 9) so much I had to buy a pair for my boyfriend (size 13) - they both fit us perfectly. Highly recommended! UPDATE: After 6+ months of almost daily use these slippers have kept their shape and surprisingly DO NOT SMELL BAD despite being worn barefoot. These are the best slippers!
