Query: Comfy

Very warm, comfortable and cozy. Perhaps not for rain but for chilly nights, perfect.Size. I wear a 6 in flats and 6.5 when purchasing a shoe with a very pointed toe.Reviews tend to be pretty much right on, so I bought a 7, besides 6.5 was not offeredat the time. Result, a tad to big, but I don't care heavy socks will work just fine.I'm very happy with my purchase and for the price they are wonderful.
