these shoes are indeed heavenly soft, but hold no piece of warm .. says on the box, you should put it in the microwave for 90 seconds, then keep warm for 90 minutes. Ha! It would be nice .. wenns goes well, they are then for 2 minutes to warm and then cool .. Very disappointing Kauf..Zwei stars that they are really cuddly bear, but not suitable as slippers, because you can not walk with the shoes / should. One can already, but it does not feel great about.
