I have Reynaud's and my feet freeze in the winter. Please recommend the warmest boots you can get? If waterproof that would be a bonus. I have seen a few old threads but those styles aren't available anymore. If there are any discount codes available even better (I got a massive code off here for Ugg Wilcox boots a few years ago and they were quite warm). I live in a city but a few people have Dubarrys and have said good things about them but they are very dear so not sure if worth spending that much. Also a brand called Sorrel (?I think) was popular. Thank you
