These are as cute on as they are in the picture.  The inside of the sock like part is plush and very cozy.  The sole feels pretty comfortable but could be more supportive.  Feels rather thin in the sole.  I ordered a whole size up and they have plenty of room.  I would have been better with 1/2 size up.  The main problem i have is that the upper sock type part is much looser than i imagined.  My calves are not real small either, and i am wondering how i can make them stay up.  I am not sure if i will keep them yet because of this reason, but they are very cute and cozy!

UPDATE:  I have had these for a year now and am wearing them now for my 2nd winter and am loving them.  I usually wear them in the "down" position, but sometimes pull them up over my pants or leggings.  They would not stay up with bare legs but with pants or leggings they work well for me (i have good sized calves.  They are very comfortable and i have grown to really like the feel of the minimalist sole (less is more).  They still look great and are very cozy indeed :)
