These are very high quality slippers. They cost more but are worth every penny. My feet get extremely cold in the winter and I live in these from Nov-Mar. I had previously gotten cheaper wool blend slippers which were not nearly as warm. Unfortunately my feet sweat despite being cold, making them even colder unless I'm wearing these which being 100% wool wicks moisture away. Good arch support too and the craftsmanship is impeccable. Really a quality product. Both my mom and mother-in-law received these as gifts and we're all addicted to our slippers now.
