I bought these because everytime I go outside in the snow to snowblow and shovel I come back in and my "waterproof" boots are soaked.  These were so very resonable and they work great.

I have a very wide foot (15 6E) and was very hesitant to purchase them since they only come in a medium, but I got a size bigger and they fit completely fine.

There is no insulation or fur lining of anykind, so I wore two great pairs of Wigwam wool socks and my feet were toasty warm and dry.
