These are comfortable and warm but seem slightly off proportionally for my feet. The top seems overly loose (see picture), and the overall effect is that I feel like I'm continually trying to keep them on my feet when walking. Front to back, they're nearly perfect. The memory foam was also a bit thinner than I was hoping for. On the plus side, the build quality is decent (only some hanging threads, also in picture), and the soles are quite grippy on my floors. I still like to wear them, but they just feel a bit off for my feet.
