Light, crumpled and warm they should be. And they are! Despite the previous reviews I have ordered me and can now, after a few weeks of use, to share my experiences. True, the rubber on the opening is quite tight at first. Therefore an asterisk less, because you can not adjust the rubber itself (drawstring for the rubber, determine Bow Front, then one way). Otherwise, my feet are warm, even if I go to the trash can so that in the cold. The slightly thicker rubber sole and the thick sheepskin, I did during those cold seasons finally warm feet and no longer slide out on my hardwood floors. Meanwhile, I feel the rubber back no more than too tight, maybe it has already widened by the constant wearing. Who knows?! I am happy!
