Soft faux fur completely lines this boot, and you can tighten or loosen the "laces" attached to the pom poms to tailor your fit.  Although it looks pretty water resistant, I plan on spraying it to give it an extra boost.  I can't believe such a nice boot could be found so cheaply!  Just got them, so can't say on the longevity of them, but I'm very hopeful they'll last at least this coming winter.
