Love them - warm. In my case i wear a 6 and got a 7 so it would be roomy with fleece socks. Almost too roomy, but they work. My only quibble with them isn't their fault - I go walking in the morning in the hills and the grass is tall -if its dewy, the plush/fur trim on the tops of these boots get soaked and then my socks get soaked.  But that's the boots fault. In cold and dry conditions they are great!
