Have had numerous pairs over the years and really like them. Only thing I noticed with this newest pair is that it seems you lightened and perhaps narrowed the sole, so they don't feel quite the same or have the same heft. I always liked that extra support. If in fact you did make that change, please reconsider for the future.
Last year, I bought myself house slippers from a local retailer. They didn't last a year. My LL Bean Fleece slippers are perfect. So far, my feet are comfortable and warm. I like them.
I have been wearing these scuffs for quite a few years. I have had to replacement them every other year as they do breakdown on the inside. They are comfortable and they keep my feet warm (I do not wear shoes in the house) !
