Initial review, basically these things are awesome. They are super warm and comfy. Pricey for a pair of slippers, but way better than the 10$ ones found at Walmart. These things seem like they'll last a lifetime. My only negative would be I wish they covered more of the heel. I thought they'd be like a shoe, but they only cover about half and inch of ankle (measuring up from the sole). These should have another inch around the ankles, both to keep them warm and to keep the slipper more securely on the foot while walking. When you walk, the back of your foot comes up and out a little, sort of like it does when you wear sandals.
