They are nice and warm.  They feel like slippers.  I have wide feet so even though reviews said they ran big, I went with my true size.  I have to wear thick socks and still my feet move around in them a little.  They are very cute and I have received positive comments from others.  The zipper comes down sometimes which can be an annoyance.  But they are so cozy that sometimes I just wear them around the house on extra cold days.
