If you want some seriously warm winter boots,then check out La Canadienne boots- the ones that are weather-proof (ie. water and leak-proof)and lined with genuine shearling. There are some lovely winter boots in their line this year.If you don't need something that warm then, Hush Puppies carries winter boots, that have a pretty good lining.As mentioned before, a leather boot (not suede, not vinyl) with a lining will work, with wool socks mixed with a wicking material. For added warmth, you can pop in a shearling insole - available at cobblers.
