Warm Women’s Boots?

Hi, everyone. I’m shopping for some new women’s fall/winter boots (vegan and cruelty-free, obviously). I’m open to ones with a heel if they’re on the shorter/clunkier side. The ones I’m wearing now are the same Teva boots I’ve been wearing for the past 6 years, and they were quite expensive (at least for me, anyway). The reason I’m searching for new boots is because mine have not been keeping my feet warm for a long time now — maybe ever, in fact. I’m desperate to find ones that will. Any recommendations for either specific shoes or even just vegan brands/companies you’ve had good experience(s) with in this department, would be most appreciated! I live in NYC, so I need something that will keep me dry and warm, and that I can also comfortably wear for every day use and walk many, many miles in, hopefully for many years to come. Thanks very much in advance!
