text: Very warm and great value! I am an 8.5 w, I bought the size 9 just to be safe with thicker socks. The fit was a little snug but not overly so. I think they will stretch or break in a little. There is no arch really that I could tell, but the grip on the sole is awesome. There is a little zipper with a thin little bag in the back of each boot? Also, make sure you release the super strong Velcro of the liner before attempting to put the boot on or you will not get it on your foot.
